Yes, agree, but the constructive solution is IPv6 itself. We need to show it (probably out of the scope of the IETF).
We need also to understand other reasons why NAT is there and provide solutions, if not available with today's IPv6. We know that NAT is used because disconnected networks become connected, because false security impression, and because the lack of enough addressing space. What other reasons are to use NAT ?
