Without thinking too deeply about it, NAT isn’t defining a protocol or any kind of specification, it’s just describing a common pattern, something that is entirely implementation detail and which can vary a lot. There isn’t actually anything to standardise in it! > This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind. Yep, that sounds completely factual to me. Is it a similar situation for RFC 9180? I’m not delving into it so I don’t know whether it’s something concretely and compatibly implementable, or just a broad description of an approach, but even if it is the latter, it probably could have been something concretely and compatibly implementable, so I’m reasonably sure it’s still a different situation from NAT, where, by nature, nothing directly connected to it is suitable for Standards Track.
