We expect those to potentially be generated from board schematics and
are not intended to be used as a universal identifier for anything.  We
do have requirements on the naming of the LED groups, which is what we
intend users to interact with.  What are you trying to use the physical
LED for that you would like some kind of consistent naming and are you
sure the group would not be more appropriate for your purpose?
