I like that none of my local devices are externally addressable unless an outgoing connection has been established. You can (and should) achieve the same thing with ipv6, but then it’s essentially just maintaining a NAT table without the translation piece. I think that makes sense in both protocols.

This can also be achieved using (other) firewall rules.

So… a firewall?
NAT isn’t a security feature and shouldn’t be relied on for managing access to hosts.
It also breaks the assumption of IP that connections between hosts are end-to-end, which requires sophisticated solutions so that everything works (more or less).
I too employ NAT to make services accessible over IPv4. But only because it doesn’t work otherwise. Not because it “makes sense”. I don’t use it at all for IPv6.

exactly, I also like this peace of mind for my home network and see no benefit in using ipv6 there. Similarly for any VPC I deploy to an IaaS.
