You can perfectly well have an IPv6 firewall in your router, not
conceptually different from the IPv4 firewall we expect to see today.

NAT is not a security measure. People presumably assume it is because it
is typically codeployed with an IPv4 firewall, but it’s the firewall
that is protecting your network, not the NAT.
