As much as I like ceph-volume and the work being done, is it really a good idea to use a minor release to deprecate a tool?

Can't we just introduce ceph-volume and deprecate ceph-disk at the release of M? Because when you upgrade to 12.2.2 suddenly existing integrations will have deprecation warnings being thrown at them while they haven't upgraded to a new major version.

As ceph-deploy doesn't support ceph-disk either I don't think it's a good idea to deprecate it right now.

How do others feel about this?
