I think there's a slightly different argument here. We aren't taking away the v2 API, probably ever. Clients that are satisfied with it can continue to use it, as it is, forever. For clients that aren't trying to do anything beyond the current basics will quite possibly be happy with that. Consumers have no reason to change over without compelling value from the change - that will come from what we implement on top of microversions, or not. Unlike the v1 transition, we aren't trying to get rid of v2, just stop changing existing semantics of it.


I'm more concerned with us not getting OpenStack projects themselves to not use the new features/fixes we are going to make after microversions land. If we force folks to use a new endpoint, then it's the same problem we had getting OS projects to migrate from v1 to v2. That took years. :(
