How do you figure that? Changing the size of the address field in the ip 
header is very much the *major* issue. It affects everything that 
networks up to and including applications (to varying degrees). Your NAT 
would still be broken, they're still be no way for the two to "talk" 
without dual stacking, etc, etc (ignoring ALGs as that's as hacky as NAT).

The fact that the IETF decided to address some warts in ipv4 at the same 
time was a good thing, IMHO.
