A lot of the trade-offs that people like to complain about IPv6 were specifically made to "rip the (backwards compatibility hack) band-aid off" and help make sure that we won't be pining for "whatever comes next" anytime soon.

The IPv6 we got was designed to be a more permanent solution, which makes it feel much less pragmatic. That's somewhat how trade-offs work.
