The problem I personally have is that I don't feel comfortable in

I think one must argue that either this is the case or is not the
case, but not leave this sort of thought just dangling. For my
part, I'll argue that no such assumptions were made, but that we
simply did what we knew how to do, and knew of no better approach.
Whether or not the assumptions were explicitly made in the past isn't
really relevant and I do not mean to imply any criticism -- I would
agree we did what we knew how to do. However, we know more now so we
should take that information into account.
A *fundamental* change between today and the world we perceive with
LISP is how we manage different types of state. Today everything is
lumped together in operational state. LISP separates that state
into two buckets and treats them quite differently.
Yes. The issue (at least for me) is how to propagate the mapping info
since we're moving the scaling thrash problem from the FIB to the
map. Pushing around the whole mapping table seems to me to have the
potential of simply recreating the problem 'later'.
