I'm not sure what you are disagreeing with or advocating.

We should expect code to change between releases, no?

As this thread demonstrated, we collectively have done a poor job of
communicating and managing those changes.

It is precisely because I expect more changes that I state that option 2 is
postponing risks, not lowering them.

I'm not saying you are wrong, or that my assumptions are correct, but I
don't understand what you disagree with.

I thought it was clear from the context of the thread and my email that
compatibility in this case is in reference to the consumers of the API and
not to the differences for managing deployments.

I totally agree that it's not a good thing.

Do we believe that keeping nova-volumes will make it painless?

Definitely!

There are also different sets of unstated assumptions about what OpenStack
is or should be that have to be resolved or we are going to keep running
into these type of situations.

Those definitely create the situation we are facing, but they aren't unique
to Cinder/Volumes, so I will start another thread.

Follow ups
