Totally agree and is the case that I call "foreign DNS" in draft-ietf-v6ops-nat64-deployment, but I was meaning that, as most of the NAT64 deployments use the WKP, changing among them doesn't break, so at least we "break less".

    That, of course, is exactly the problem with RFC 7050. If you are using the preferred resolver, you get one prefix, and if you're using 8.8.8.8 (as many do), you get another. A Well Known Prefix is a great way to pick the wrong one, or one that doesn't exist.
