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. > > ceph-volume has been present since the very first release of Luminous, > the deprecation warning in ceph-disk is the only "new" thing > introduced for 12.2.2. > Yes, but deprecating a functional tool in a minor release? Yes, I am aware that ceph-volume works, but suddenly during a release saying it's now deprecated? Why can't that be moved to the M release? Leave ceph-disk as-is and deprecate it in master. Again, I really do like ceph-volume! Great work!
