It up to BEHAVE to see what, if anything, needs specification here.  I am still not convinced a problem exists here for which the IETF has to do anything about.  I am definitely convinced on the referral IP address that Brian mentioned in that the referral needs some thought.

Please come to the GROBJ BOF in Hiroshima. Basically, I would
argue that all addresses have to be regarded in some sense
as transient (and that most applications are defective in this
respect). It's particularly acute, as Brian H said, in the
case of referrals.
