As to the established stars who still haven't, maybe there isn't the same pressure from studios and/or agents to do a first anal, and/or the performers are much more confident in saying no to those scenes. Then there are those performers who want to be doing anal, but are struggling to get toys or dicks up there in their prep (Valerica Steel is a recent example of this, and before that great moment in 2015 so was Riley Reid).
I still think that we are getting enough good names per year, but definitely not as many "big" ones as we used to. I also think that the studios don't seem to be as focused on first anals as they used to be. Tushy and Tushy Raw don't do as many, all but 1 of Mike Adriano's sites are no longer updating, Brazzers and their sister sites don't do as many as they have in the past. Evil Angel aren't doing as many as they used to, and it can't all be explained by Adriano's departure around 5 years ago. Is this because they have shifted their focus, or is this because the number of performers willing to do these firsts with them has dropped off?
Always feet n ass. In that order.
