Again, I think that it is unfixable and that development efforts are better focused
on getting the IPv4 only hosts onto IPv6 as that IS a workable solution to the problem
where NAT444 is an awful hack made worse by layering.

IPv6 deployment is the only thing that will cut down on the operational and support
issues enumerated. Trying to fix NAT444 is like trying to use more gas to get yourself
out of the mud in a 2-wheel drive automobile. If you take a limited view, you might
think that pushing harder will help, but, in reality, you're just digging a deeper hole.
