They are, the problem is mount explicitly skips them (see
util-linux/mount/mount_by_label.c::uuid_cache_init...)

                ...
                for(s = ptname; *s; s++);
                if (isdigit(s[-1])) {
                        ...[do good stuff]...
                }

and right there we've skipped over anything thats not a
partition.  Why mount does this, I have no idea - we'll
have to ask Andries (aeb@xxxxxx), the util-linux guru.

cheers.
