I can definitely agree with that. My favorite part of reddit was everyone's niche interests having large groups, and sometimes seeing those groups make it high enough to see -- and then getting to learn about something I'd never thought of even existing before.

I agree. Also, there wouldn't be a need for any rules changes to this subreddit for that to happen; I imagine eventually a dedicated Nuzlocke community would pop up out of desire to be in community with people with that expertise, not out of a desire to keep that content out of this community.
