Not sure that's reasonable.  We have at least one extension in contrib
that creates objects in pg_catalog.  ISTM that's enough precedent that
more could be created in the future.  (Now of course extensions get
special treatment anyway, but my point is that there's no prohibition
against creating objects in pg_catalog.)
