that is kinda my point, this feels like you define modern as 'rules I like', including your 'why is AW modern' post, like
"10: Every campaign I've run has come to a natural end after 6-12 sessions with character arcs and character development that weren't pre-planned but are strong
9: Every roll has consequences. Success, success-with-consequences, or hard move
8: Everyone gets to cheat death a few times. Perma death is something I haven't seen."
why are 8 and 10 modern? Simply because it is different from how BX was played? I see no reason why 5e is more modern than 3e, to me it took a step back towards 1e/2e in many ways. Is it more modern than 2e? sure, More modern than 3e or 4e? Not really, just different.
