I know I said I was finished, but... then why not just say the DM determines whether a creature is or is not aware of the effects of a power? I mean isn't this what is ultimately (in a roundabout way) being given as the "proper" way to do it by most?
Because that would be a different thing.
I'm with many others in not seeing why you regard "aware that XYZ" as equating to "acting rationally in light of the awareness that XYZ". This equation isn't true even for most human beings - why would it be true for an ooze?
I don't think anyones arguing from a hard simulationism of the act of playing music though. They're just saying they want a mechanical ability that states they are a good musician...
This goes back to the "flag" issue. If it is just a flag, then why not just write it on the sheet? Unless you have some sort of
resolution system for being a good musician, why is it important to spend PC-build resource points on it?
Or are you envisaging that the resolution system would be d20+skill and whoever gets the highest score gives the best performance? But this then gives rise to the question that Crazy Jerome in particular has talked about, namely, how are we going to cost that skill in a fantasy adventure game?
To come at the issue from a slightly different angle - the game has no "I'm a noble" skill. Yet presumably being a noble makes a difference in some challenges - everything else being equal, commoners may be more likely to listen to someone who instructs them to address him as Your Grace, for example. How would you handle this in a skill challenge? Perhaps grant a circumstance modifier to the Diplomacy check in question - +2 for an obsequious audience, -2 for rebels. Anyway, however you would take into account this non-mechanically represented element of the fiction in resolving the action, take a PC's background "skilled musician" into account in the same way.
if a skill doesn't exist in the game, a challenge to that game cannot be performed within the game's mechanics, end of story.
I don't think this is true - see below.
Your Bard and Bob's Warlock and Suzy's Warden are all musically inclined by background, while Marco's Paladin is not.

Marco's Paladin is out. That's cool.
But the other PCs have no meaningful distinction between the others. By rule, there is no skill to reference, thus there is no distinction between trained or untrained. All it is is a battle of stat bonuses. Literally, no skill is involved.
No PC-build element called a skill is involved in resolving the challenge mechanically. That doesn't mean that no fictional skill possessed by one or more of the PCs is involved.
The easiest way to resolve your contest would be for each player to roll a d20 and add CHA - hey, now we'ver found out that Suzy's Warden is a better piper than Bob's Warlock!
There are other, more sophisticated ways it could be done, too.
No.
In lieu of a Poetry skill, I used raw Charisma, Diplomacy, Intimidation, and Insight to represent my PC's poetic ability.
That's all. I said nothing of requirements

Use a character's adventuring skills to represent various kinds of non-adventuring abilities.
Arrrggh. NO. This is where the breakdown comes every single time this conversation comes up. Mallus' paladin uses those three skills plus charisma. Why? Because Mallus says so.
It's going to come down to what is believable to the group at that time. If the player can pitch a good justification, whatever that justification is, then groovy.
If you can justify using your best skills for a given task, where's the problem? OTOH, I play with mature players who aren't going to accept "cos I said so" from anyone at the table. It works both ways. The players are invested in finding ways to not break immersion, every bit as much as the DM is. So, the player isn't just going to pick his best skill (Thievery) and then try to justify it, because, well, that's lame.
Unforunately I can't XP these excellent posts.
