There is no need to worry about this deprecation, Its mostly for
admins to be prepared
for the changes coming ahead and its mostly for *new* installations
that can plan on using ceph-volume which provides
great flexibility compared to ceph-disk.

a) many dont use ceph-disk or ceph-volume directly, so the tool you
have right now eg: ceph-deploy or ceph-ansible
will still support the ceph-disk, the previous ceph-deploy release is
still available from pypi

b) also the current push will help anyone who is using ceph-deploy or
ceph-disk in scripts/chef/etc
   to have time to think about using newer cli based on ceph-volume
