Most of my users are on cell phone browsers :)

Furthermore, i can choose which ones get ipv4-only NAT44 and which get
ipv6-only + NAT64

Now, only if there was major cell phone OEM support ....

Also, i would like to extend the idea that as IPv6 becomes dominant in
the next few years (pending access networks), the need for IPv4 access
will wane and LSN for the IPv4 will become more acceptable as IPv4 is
just the long tail.
