sounds great but it fucks up P2P in residential connections, where it is mostly used due to ipv4 address conservation. You can still have nat in IPv6 but hopefully I won't have to deal with it

The NAT RPC talks purely about IP exhaustion.

What do you have in mind.

Rather, NAT is a bandage for all sorts of reasons besides IP exhaustion.

Example: Janky way to get return routing for traffic when you don't control enterprise routes.
