Bogus.  The reason is that they haven't been pressured into adoption by
higher powers; so we will get into a nice scramble to migrate in a
pinch.

"most people" have no idea what NAT is, don't care, and shouldn't have
to care.

Some people's belief that NAT is some magic sauce that makes them more
secure [it does not] or provides them more flexibility [it does not]
than real addresses ... causes the people who understand networking to
have to spend time explaining that their love of NAT is misguided and
their beliefs about NAT are bogus.
