Hmmmm, the code may be there, but I suspect that not all of it will
apply to v6 and be used.

I suspect that depends on who you ask. Security is always the top of my
list. That being said, what security is there in removing NAT from v4
because it broke what the customer wanted to do? Then they are back to
their host based stateful firewall; which apparently everyone believes
is not good enough. Might as well throw in v6 and trash the NAT.
