I don't agree that not many people are concerned with RC now, but you are right, the dust has settled after hf20 quite fast. Maybe 2 weeks of complaining about the worst implementation ever and now silence.
RC is actually quite an issue for new people not wanting to put a hundred bucks in this platform first. (because they have so little and need to wait quite a lot for being able to post and comment on a continuous basis which sucks and drives them off en masse)
I think the RC issues are getting cleared up through applications, not on Steem. The delegation pools need to happen for them though.
