Good for you. It's still strange to me that you can call it 4e and prefer it to another edition when throwing out at least 50% of the rules and design, but if you are happy doing it. As for me, it would be way more work doing this than any other edition, so call me lazy...
If they play it like a boardgame, then why not, it's still a way to play the game, they are still missing power cards though.
You should really read them, you know.
Again, please read the rules of 5e. Non-combat challenges, Milestone advancement or even levelling without XPs are not even options, they are core rules.
No, it's not, sorry, please read the rules.
Good for you, I can play 5e without any experience at all, just out of the box.
And we are speaking here about the core game design. If people are happy running a game completely against the core design, good for them, they are (probably rare) counter examples.
You can apply everything to anything (and the other way around), but if you look at answers from other 4e proponents, they usually like the rules because it allows the PCs to decide what they can do and avoid litigating with the DM...
I DM 5e, thank you very much. I also have read the rules...thank you very much. Yes, I know what I'm talking about regarding 5e.

[Edit] From everything you've said, it appears that you play fast and loose with the rules (which is okay, and it is okay to play any version fast and loose. WE should accept that there are those that play strictly by the rules, and those that play fast and loose by the rules. Both methods are okay for playing RPGs (we should be able to play the game in the manner which we enjoy), but we shouldn't accost others for the way they play and call it the wrong way to play.
Most of the items in 5e got their origins in 4e, but they painted them over with gloss so to bring back the players of 3e. 5e has a page or two on other ways to get XP, for 4e it was the BASE assumption. XP did NOT come from Monsters, but from encounters. Monsters were just one type of those challenges, but there were far more than that. Situational, Persuasive, NPC's, challenges, traps, etc.
It was rated on a level system (that many people disliked, but it is what it is) which gave XP depending on the Challenge of the Encounter. All that determined whether something was an encounter was whether there was a risk of failure. If there was no risk, there wasn't an Encounter that could give XP. If there WAS risk (let's say, trying to trick a Noble into letting you go through their lands) of failure, it could count as an encounter.
I could go into great detail on how 5e took many of the items of 4e directly into it's core (for example, proficiency bonus is directly from 4e's proficiency system, but spread over 20 levels instead of giving the +5 bonus right off the bat, and using the proficiency bonus for combat as well), but that would take someone with an open mind on how the various editions of D&D got their basic core (in general) from the edition right before it (the same actually applies to 4e from 3. too, the basic core of 4e is pure D20 and easily converted from 3.5 if one wanted because they are similar).

Much of what has been said about 4e can be said about 5e and be correct. (Edit: an edit to this post as I have read the rest of the thread this comment no longer seems applicable).
PS: It may interest people that...yes, they actually sold "power" cards for 5e when it first came out years ago.
Not sure how many are still being sold, but I think at least the spell cards are still sold. These can be used (if I recall) currently with the Fighter, Paladin, Cleric, Druid, Warlock, Wizard, Rogue, Bard, and Ranger classes. So, these days you are out of luck if you play a Barbarian or Monk, but otherwise, you can get Spell (some could even call those "Power") cards for your class of choice if you so desire.
