Yes, we envision global switch, though some projects may choose to
wait for another cycle to see how it works for pioneers.

Eventlet has lots of flaws, though I don't see it replaced by asyncio
or any other mechanism this or even the next cycle.

There is lots of work to do to replace it. Switching mysql library is
a 100 line patch + performance benchmarking to avoid regression.
Switching async library is thousands of LOC + refactoring + very
significant work on oslo side.
