Don't think I have ever disagreed.

Yep.   I have a pretty good model of how most users use their phones. That
said, ipv6-only + nat64 only works well for most users (90+%).  For the long
tail, ipv4 services are not going away.

I believe that the user should be allowed to select their address family
easily ... this is easy in the mobile world.

Most folks (web and email) should not care if they have ipv4 + nat44 or ipv6
+ nat64. For those that do care, there are pros and cons to both. I prefer
the latter since it brings back e2e and is a positive incentive for ipv6
adoption
