Oh, I do that too.

But to your point about not cheering on NAT, well I will because I see NAT as useful tool.

It is not an opinion well aligned with the preferences of the IETF. But the purist model of transparent end-to-end networking has never sat well with me. It’s just not a thing we want.

So because you don't want it means that nobody can get it?

Because that's what happens if you advocate for NAT by default. Conversely, with "IPv6 + inbound-blocking-firewall on CPEs by default", everybody gets the same behavior by default, and people that want something else can get that instead.
