OK, let's go a bit further with the case of marking the v3 API stable in
Juno. If we did that, what is a reasonable timeframe of v2 being
deprecated before it could be removed?

immediately". From a selfish user perspective, the answer is "never
remove it". Where is the reasonable middle ground? How long would it
take to have enough clients migrated that we could remove the old API?
I'm interested in answers from pretty much everyone on this, including
deployers, as well as users of our APIs. I'm also especially interested
in an opinion from large public clouds based on OpenStack.
