How about adding a easy-to-type symlink for MAC named devices? Would
that work? Then users could refer to a device by the persistent MAC name
enx112233445566, but also could use a short name like eth2 (which might
not be persistent).

It would be similar to hard drives. I used UUIDs in /etc/fstab, but
short names like /dev/sdb3 when calling mount on the command line.
