I think we certainly should wait for at least beta1 (not that we have a choice
now), to make sure all of this gets at least some coverage.

I guess I'd say "the community". I think it should depend on how many problems
we find, be it correctness or performance regressions. I don't know how to
make that call without seeing how things are going during beta.
And yes, I think this should involve some benchmarking too - generally a good
thing to do during beta, and if it involves AIO, all the better.

More testing would be welcome!
