I never mentioned root=. For everything *other* than root filesystem
mounting, the code to look at is libblkid, which supports both LABEL= and
UUID=. That's what mount(8) uses.

Raw non-initramfs/initrd kernel root= parameterwise, all that is supported
in /dev/{fake device name}, root={major:minor}, and
root={major*256+minor}. This is of course yet another reason to use an
initramfs, which can easily use normal mount and/or blkid directly to
support whatever permutations of LABEL=, UUID= or whatever you prefer.
