Some of them will know you're doing it and get pissed off

NAT64 is a temp bolt on and also not the same thing. If I own 1.1.1.1 in v4, that doesn't mean I own some equivalent of 1.1.1.1 in v6. They had router nat64 and relay nat64, both with dealbreaker problems.

You don't exactly need a translation layer. If they just gave me 1.1.1.1:: in v6, anyone migrating v4 to v6 would have the same route to me as before, and other changes like DNS6 could be gradual. Then after v4 is abandoned enough, I can sell 1.1.1.1.2:: to someone or use it instead of NAT.

SLAAC is a good design as a non-default that people who know what they're doing could enable, but a lot of people don't even want public v6 addrs for hosts, they just want NAT/DHCP.

There were some choices of v6 that made it extra hard, like declaring all v4 addresses no longer valid in v6, or making slaac default

It'd be annoying even in the scenario where it got quickly adopted. Complicated spec, user-unfriendly addresses, unclear defaults.

I've never seen a GSD actually obey the drop/aus command without you having something to trade for
