So what's keeping the futex2 code from doing all that futex1 does so
that the futex1 code can be deleted internally?

I'd much rather see it the other way around. Much of what futex2 does
can already be done with the futex1 code-base. And then we can add
features on top.

Yeah furthermore, how can futex2 be thought of replacing futex1 in the
future when the PI aspects haven't even been mentioned?
