[ceph-users] Ceph 16.2 vs 18.2 use case Docker/Swarm LXC

Could I be missing any significant features when using Ceph 16.2 instead of 18.2 when using Docker/Swarm or LXC? I am asking, because I am struggling to set it up in Version 18.2 due to confusion with the debian 12 packages as some still stay in version 16.2 even after adding the sources for 18.2.
