I have not found subcommunities inside a community. But I think this should be possible to build in the future.

So, as you say, less judgment, perhaps, with the community, but we'll only know to what extent that really is until we get there, and no doubt, the way things go around here, if one community is routinely receiving higher rewards over others without reaching that magical value ratio, I'm sure there will be unhappy people outside of that community who will try to shut it down (if that's even possible).

On a STEEM level that should always be possible. But when a community uses an SMT it shouldn't. Tribes already have shown this.

I think communities on steemit.com will be a huge improvement.
