Context:

People have been asking for IPv6 Support on GitHub since years (probably a decade by now)

... and someone even got so annoyed that they decided to setup a dedicated website for checking this: https://isgithubipv6.live/

You'd better hope that you can NAT ipv6 because if you aren't behind a CGNAT and then your LAN is completely exposed without a NAT you're very likely going to have devices exploited.

NATs on people's boundary has been doing pretty much all of the heavy lifting for everyone's security at home.

The word you are looking for is firewall not NAT.

NAT does not provide security whatsoever. If the NAT mapped your (internal IP, internal port) to a certain (external IP, external port) and you do not have a firewall enabled, everyone can reach your device by simply connecting to that (external IP, external port).

I haven't seen routers that do not come with IPv6 firewalls enabled by default.
