Thanks.  That keeps the device-extension association in one place, at the
cost of a little redundancy if done manually:

  [0010b5c1867c]
  setvar = HEREITISAGAIN=0010b5c1867c
  regexten = 543

I've coded (but not yet seriously tested) an optional feature that would
basically automate just what you suggested.  It'll be interesting to see
how many think this is useful.
