Indeed, the transition to IPv6-only networks is a timely and important step, and this is an interesting approach. In my opinion, NAT64 in combination with DNS64 presents the most practical solution for home networks. This approach can be fully implemented by consumer routers, eliminating the need for any changes to client devices. If router manufacturers were to make NAT64 with DNS64 a default feature or, at the very least, an easily selectable option, it would significantly advance our progress toward widespread adoption of IPv6-only networks.

clatd https://github.com/toreanderson/clatd/ is a nice and practical CLAT implementation: it does not "require" dns64 but can use it for single stateful translation instead of double
