to me, the main difference is that the 'multiple interface' issue
is not bound to mobility, and more specifically to mobility
protocols (mobileIPv4, mobileipv6, nemo, ...).

Therefore, the MIF work is not scoping about mobility protocols and
shall not require mobility protocols.

I would see that if some part of the MIF work is looking at the
mobility protocols, then these should be then "transfered" to MEXT.
Even without mobility considerations, the issue of how to handle
multiple interfaces overlaps with IntArea, RRG, and Behave (those are
the ones I can think of offhand).  Have you seen the arguments, for
example, about session initialization when multiple addresses can be
in play simultaneously at both ends?  I apologize but I still don't
understand the MIF boundaries.

I wrote a draft a long time ago about the problems for selecting the
source address in multiaddressed hosts, not sure if this is related to
what you asking about...

you can check it at

http://www.watersprings.org/pub/id/draft-bagnulo-6man-rfc3484-update-00.txt

there is an address selection design team that is looking at this currently.
mmm, not really
maybe i missing somehting, but i understnad that the scope of the design team is limited to the automatic update of the rfc3484 policy table, and they are not dealing with the issue of how the properly select the source address, for instance, in the case that you need to retry due to ingress filtering and the like
