 [Update: it seems this is already reflected in the PEP. I wonder where the requirement for "a new type" comes from. I think making it a module should be conforming, even though probably discouraged for cpython, as it would make people think that they can rely on it being a module.

That stems from people arguing over whether sys.implementation should be a dict or a tuple, and people going "it shouldn't be a sequence since it lacks a proper order", but then others saying "it shouldn't be a dict because it isn't meant to be mutated" (or something since I argued for the dict). So Eric (I suspect) went with what made sense to him.

Yep.
