I tend to agree with Wido. May of us still reply on ceph-disk and hope
to see it live a little longer.

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.

ceph-deploy work is being done to support ceph-volume exclusively
(ceph-disk support is dropped fully), which will mean a change in its
API in a non-backwards compatible
way. A major version change in ceph-deploy, documentation, and a bunch
of documentation is being worked on to allow users to transition to
it.
