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.
