That one's a bit of a culture shock for me coming from Pathfinder 2E, but over in the D&D 5E world it feels like they take away your 'DM Card' if you don't have at least 73 pages of houserules BEFORE you even buy the DMG.Something that is bugging me slightly and I am not even sure why: over on the daggerheart subreddit, tons of people are going all in on homebrew and houserules while admitting to not having played the game at all.

Critical Role also, hasn't really been following the rules for years from what I gather reading comments. So it's fanbase may have no experience or expectation of ever even thinking that wat.
And lastly, Darrington themselves are going all in on being pro-homebrew. Both in what you run and how you look a the rules. For 'homebrew' the campaign frames and comments about re-styling things are written in a 'make the flavor your own' mindset.
For houserules, I think that just carries over with the flavor of the system and the fact that they had day one playtest material for 'new stuff' which kind of makes the point for the idea of it being a system they expect to be modified often and a lot.
