I handwave past all that by pointing out (as you have) that 
stateful inspection is just a subset of NAT, where the inside
address and the outside address happen to be the same.

(in the same way that the SHIM6 middleware boxes which were 
proposed but never built were /also/ just subsets of NAT, with
the translation rules controlled by the SHIM6 protocol layers 
on the hosts... but we weren't allowed to call them NAT gateways,
because IPv6 isn't supposed to have any NAT in it :)
