I wanted to research this question, took me a bit.

The non-udev case you mentioned is the only reason I could 
make out for going with UUID= rather than /dev/disk/by-uuid/.

Those systems rely on mount using blkid to find the matching
partition and mount only does it itself when the UUID=
notation is used in fstab.
