I do wish there was a better path for like... Actual new editions in D&Dlikes, without massive engine changes. I still pine for say, a 3.5 release with a Warbladelike as the fighter, the assorted multiclass fix feats worked in, a new pass at classes/skill usage based on all that new development. 3.5 and PF1 were the closest we came to that kind of update, and they weren't really the result of taking X years of development and reworking/curating so much as outside business needs both times.
I'd really like more attempts at integration and improvement without blowing up the world. I think there's definitely some point where no one is going to be upset about starting over (10 years feels like plenty) and PFs wide open SRD mitigates that even further.
