I can't promise what 3GPP will do.  (Heck,< i can't even speak for what 
my employer wants from this.)

But I think it is useful to have the conversation with them.  I have 
talked to some folks involved, and believe that if we come to agreement 
that the change is useful, we could have a good discussion as to whether 
they agree.

Yours,
Joel
