Agreed.  I think it would be a serious mistake to clutter
4409bis up with some of the details that have been suggested.
Even at full standard, authentication details are best
incorporated by reference to other documents than can be updated
when or as necessary.  Further, I share John Levine's
dubiousness about the value of AUTH EXTERNAL, which may argue
even further for isolating discussions about it and its
relationships.
