Desktop volume management stuff is already doing it. When I connect my
ipod, it shows up as IPOD on my desktop regardless of which sd letter it
gets. Also, recent distributions use LABEL= tricks to find out root and
other partitions to mount on boot.

The major/minor number and device name (which is determined by udev)
aren't that important already and will become less of an issue as time
passes.
