> I always forget the Engine-side semantics of supportedENGINEs and clusterLe
Not true. 

in engine terms:

- clusterLevel dictates which HSM verbs/verbs you're allowed to use (e.g., hotPlugDisk) 
- dcLevel dictates which SPM verbs/features you're allowed to use (e.g., POSIX storage domains are not supported in 3.0)
- supportedENGINEs dictates what API calls the engine will use on the connected VDSM REGARDLESS of dc/cluster levels. validateStorageServer is one of these. There should be no problem having a 3.6.0 engine communicating with a 4.18.* VDSM on a cluster and dc level 3.0 - restricted to NFS only, with no hotplug features, for example.
Line 37:     'supportedProtocols': ['2.2', '2.3'],
Line 38:     'clusterLevels': ['3.0', '3.1', '3.2', '3.3', '3.4', '3.5', '3.6'],
