PoB isn't finished yet. I believe we all know that there is an issue with DVs that can be tweaked better. We had a 5min window for years that literally made no sense to me, and we finally lengthened it, and now it's much better. We can't remove DV's, but we can tweak, add outside systems that can help people being abused, and start exploring ways, as a community reaching consensus sorta like a proposal in the DAO, ways to punish obvious abusers of DV's. This is going to be a focus of mine going into next HF.
