IPv6 nat is a thing that exists and is used. IPv6 purists like to imagine it doesn't exist which is cute.

It’s extremely rare compared to v4, where it’s more common than not. I haven’t seen it with a single consumer ISP, and why should they use it?

Not up to you as a hole puncher to decide what a network uses. You just punch holes. IPv6 doesn’t allow you to skip NAT unless you are comfortable with your code not running everywhere.
