Why are you under the impression that every single thing called a
UUID must work as a *filesystem* UUID?
Lots of things have a UUID. Universally Unique IDentifiers are
useful things. But not every UUID is a filesystem UUID. This is like
taking the VIN from your car and putting it in fstab then asking why
it didn't mount your car as a filesystem.
MD arrays aren't filesystems, they are block devices.
"blkid" does report filesystem UUIDs, according to its manpage, so
the answer to that one is is yes.
