I admit, this conversation, as its evolved over 18 pages is simply baffling to me - especially the ongoing objections CapnZapp has WRT the skill and feat design of PF2.
How is the below simulated exchange not a viable approach to PF2's skills and Feat "bloat".
GM: you are in a room with a chasm between you and the far door, hanging in the middle of the chasm is a chandelier.
Player: I'd like to swing across the chasm on the Chandelier
GM: OK, awesome! do you have any feats that will help you to get across?
Player option 1: Yes, I have a Chandelier swinger feat
GM: [either knows the feat or looks it up to understand how it works] OK, cool. make an acrobatics check, DC 20.
Player option 2: yes, I have monster surfing feat, which if you squint hard enough and loosely interpret
could be used for this exact situation
GM: either: sure, that sounds cool, and PC's being awesome is "fun"; or sorry, that feat doesn't apply in this circumstance you'll need something else. you can use acrobatics at a DC of 20 to try and cross. the "sure, that sounds cool, do it" answer is the only case where the GM may have popcorn thrown at him - especially if 2 PCs are attempting the same thing, 1 with Chandelier swinging and the 2nd with monster surfer. adjudicate on the spot, back out of a potentially bad call once you get more information and move on...
player option 3: no, I don't have any feats to help me here
GM: [either I know there may be a feat that can support this action, in which case, I
may increase the difficulty of a no-feat attempt, or I don't know (
or don't care), and keep the DC at 20] OK, make an acrobatics check at DC 20.
player option 4: no, I don't, but can I try and do this with Society?
GM: no but maybe someone else can attempt the crossing with a feat or acrobatics instead? [PC brainstorming ensues]
if you have players that are anything like my players, they will:
a) chime in at decision time, letting the GM know about the special Chandelier swinger feat that THEY have. "hey, I have the chandelier swinger feat, can I try it also?", or "why are you letting him try this, they don't have the chandelier swinger feat", or "cool, let me tell you about my knowledge of PF2, by referencing the chandelier feat". any of those are signals to me, the GM, that someone has invested in this feat and therefore someone without it should likely have a higher DC, or the player with the feat more likely have a lower DC for the task. IME, players are not at all shy about speaking up about the awesome things they have, or object if I step into their niche by allowing something for another PC that they have invested in...
b) Grub for any advantage they can get to simplify this task, aid others, spending hero points, and like literally weaving all their stowed 50' lengths of ropes into a net

...
I have
never had a group of players who, when facing a chasm and a chandelier, simply walk away because, you know, nobody picked up the feat. mission failed, adventure over. this is 100% of the time a situation where the time a GM informs the player they can't do something. the failure state here is not the players, its not the rules (as the rules have AMPLE allowances for on-the-spot rulings), its the GM.
worst case scenario here. I as GM, "allow" someone to attempt to swing from a chandelier without a feat (oh god no!!), at a DC that would have been similar to someone who spent feats on having this skill. Now, this contradiction is VERY likely to only happen only after time passes - for example. in one session I allow the swing without a feat, 3 months later there is a similar situation where a PC with the feat tries it and the inconsistency is noted (
if remembered at all), OR a player after the swinging "incident" takes this feat and then objects to the past ruling, with a "well actually..." comment.
"hey GM, why did you let player A 3 months ago swing across with their acrobatics skill at a DC of 20, but this time, when I do have a feat, you are making me roll against a DC of 22?"
"hey GM, remember 3 months ago when I swung across the chasm, and you let you use Acrobatics for this. did you know there is a Chandelier swinger feat for this and you shouldn't have allowed this?"
what should I do? Is PF2 broken? has my responsibility of GM needing to memorize thousands of pages of text ruined the game? no, I answer thusly: "yeah, my bad. sorry, it was a call in the moment. the next time we need to swing across chandelier's you remind me that you have a feat for this, OK? thanks for keeping me honest

".
This is a collaborative game where the GM is supposed to
be on the players side. a game about
heroic moments when swinging from a chandelier is
supposed to be attempted, be epic, and to make players feel awesome. limiting these heroic moments to situations when
only players who, at the exact right moment happen to have specific feats - WHEN NO PLAYER HAS ACTUALLY PICKED THIS FEAT - is bad gm'ing (yup!). expecting only the GM to know every feat is an unreasonable expectation and an undue burden to place on the GM - players should know their Character's capabilities and advocate for their use thank you very much! If any player is going to rage quit because I made a ruling that supported fun over slavish literal interpretation of feat lists - then this is not a player I'm interested in having in my group to begin with. the notion of the GM needing to know 1400 feats (or whatever the number is) in order to play the game or to play (any) game "correctly" is, simply put, a logical fallacy that says more about your mindset as GM than it does about any game "system".
Literally
asking the player if they have any feats that support the action, otherwise, as GM, simply consult tables 10-4, 10-5 and 10-6 with maybe a quick reference to the skill and the training levels is all that you need to play the game fairly and consistently...
its this easy:
"I would like to do x"
"do you have a feat to support x"
"yes I do" or "no I don't"
Adjudicate accordingly, and accept from time to time, you may screw up, but likely the screw up will be in favour of the PC and them having a great, awesome, fun time...
[shrug]
ya, but, what about the chandelier swinger feat and taking away its agency within the rules???? well, if nobody picked it in your game - THE FEAT FUNCTIONALLY DOES NOT EXIST, and if someone did, you are guaranteed that the player will tell you they have it and its important to them! how is this hard?

note 1: totally recognizing I too just spewed a bunch of stylistic nonsense about how
I run my games, and to each their own and all that. but I honestly read these posts and feel like I must not know something inherent about a certain unwritten style of Pathfinder play, which my laissez faire style seems anathema towards
note 2: I recognize what I said above would get me fired from Organized play, as those game runners
should have a better command of all the rules. but I play in home games, not OP, so [shrug?]
