No, maybe this is a misunderstanding. MIF is really not assuming 
anything like that happening. The charter text simply notes that such 
work exists and that its not MIF WG's place to develop those further.

The MIF charter did not mention PMIP specifically, but the list was not 
intended to be complete. Multiple care-of address work in Mobile IPv6 is 
already being standardized, and PMIP multihoming is under consideration 
(currently heavily debated).

In any case, MIF does not rely on Mobile IPv6 or Proxy version thereof. 
Those efforts are proceeding independently.
