Which is what ISP are doing with 464XLAT deployments. IPv6-mostly networking and IPv4-as-a-service are things that are happening in real world right now.

Yeah in Japan my ISP even lets me choose which IPv4 provider I want to use, as the fiber network is IPv6-native and IPv4 is "just another service" like IPTV.
