   I don't even see any reason to change the default behaviour,
   and I really only care that the standard says "the server MUST
   use the client-identifier if supplied" in so far as that might
   cause ISC to not consider a config option which, if activated,
   caused said non-standard behaviour.  And speaking just for myself,
   even that level of caring is quite small as I can easily make the
   change locally myself.  Others, obviously, have different abilities
   and management environments.

   Understood and appreciated.  Truly.
