But we should not have a dm only solution.

For that many disks, I don't see how it helps much, you must still deal
with the specific id's at some level. I was thinking more about nice names
for a few disks, or splitting disks into groups with a common prefix (and
then still keep the long id portion).

Enumerating names in shared/cluster setups probably makes things worse,
though you could try to share or copy the file that maps wwid to the
enumeration, the same thing for a udev solution.
