This whole discussion seems permeated by some sort of fear (or at least concern) that letting players establish fiction - about their PC's backgrounds, or relationships, or loyalties, and the like - will somehow break the game. But how? Surely most GMs have ideas for scenarios for a Devotion Paladin other than having to choose whether to foster or slaughter the orc babies?
I imagine just like some players (includes DMs) of the game prefer to play with minimal to 0 house rules (and we do not necessarily object to that), there are certain players (includes DMs) that prefer to play true to setting hence the desire not to create characters and/or backgrounds that go against type.
