I pretty much agree with this; I expect that working out the
details will be pretty tedious and perhaps even contentious.

I agree we can't "change" 3GPP architecture in the IETF, but
we can respond to the needs which are evident from considering
the 3GPP architecture.  It seems very few believe that LTE
is really immune from further evolution and even significant
change in the future.  If IETF does NOT respond to the needs made
evident in current 3GPP specifications, we have little hope of
proper integration into their future evolved designs.
