Using "AD is secure" add extra complexity.

Another big issue with NAT-PT: you can not use it
to enable an Ipv6-only resolver to query data from
an Ipv4 only DNS server... (in the general issue to make
DNS interoperate smoothly between IPv4 & IPv6 only worlds)

Also, as i explain earlier, NAT64 scales better.

you still haven't convince me about the severity of those problems.
I think I made clear today that those issues can be addressed.
