What I'm curious about is how community subs will evolve - like how s/GenderCritical has already been made restrictive and ban-hammer-prone in exchange for removing themselves from s/all. Their description does say that they will create a proper GC debate community however.

I wonder if we'll start seeing subs appear in pairs: one being a restrictive, community-focused sub and the other being the open, debate-oriented sub (or perhaps subs that focus on the debate between two communities like r/GCdebatesQT instead of broad categories that would be something like r/debateGC).
