Yeah, it's definitely not what the ABI is for and probably more trouble
than it's worth.  We *could* probably write some helpers that handle
legacy supply names to the regulator core code if someone really wanted
to retire old names, that way the complication would be shared between
users which seems more managable but someone would still need the time
and enthusiasm to write the code.
