If we try to kill 2 birds with one stone, we'll probably miss both.
I think we should be aware of the mobility side of the topic, but
I am not so sure we should make sure we explicitly state that we will
solve both.  I do think we should be aware of the mobility properties
of any possible solutions, but I have my doubts that the IETF can
solve problems that are less than extra-crispily defined.
