It's either a new builtin or affects the API of an existing builtin, and it is moving something from a compile time error to a runtime error. Things that fall under the moratorium aren't "special refactorings" - they're anything that affects the builtins or the language syntax, so trying to separate out this one part of PEP 380 fails on both counts. Coroutine programmers have lived with the status quo for years already, putting up with it for a couple more until PEP 380 goes in isn't going to hurt them all that much. On the GeneratorReturn vs StopIteration front, adding a new builtin exception is a big deal. "Newbie programmers might not notice that their return statement isn't doing anything" isn't a particularly good justification for adding one.
