IIUIC, the upgrade path for Ceph across Ubuntu LTS releases relies on the Ubuntu Cloud Archive [1,2,3], which provides Ceph packages (and more) from newer Ubuntu releases (non-LTSes + next LTS) in LTS releases (similarly to what you described, a 'repository for distro+ceph users to do upgrades'). So, users can remain on the same Ubuntu LTS release to perform Ceph upgrades, either periodically/sporadically as newer Ceph packages are available from newer Ubuntu non-LTS releases or say, cumulatively, going through those at the time of the next Ubuntu LTS release. This also allows testing the next Ceph version first, before doing a distro release-upgrade that provides the same (tested) Ceph version, which helps to reduce risk in the overall distro/ceph upgrade process. I'm definitely not experienced with Ceph, but I've seen a few bits of this while working here and there. Hope this helps!
