I don't understand your surprise.

In the first scenario, without added ceph nodes, Proxmox subscription 
will support ceph storage server too. If you add non-Proxmox nodes, they 
can cause trouble in Ceph server duties.

In the second scenario, Proxmox subscription will support only ceph as 
client, but not ceph storage nodes...
