If in a year people come back and have some examples of where a proper scheduler would help improve speed on multi-core systems even more, then we can address the issue at that time.
Exactly my feelings.
Although I don't agree that the problem of I/O convoying is merely some "theoretical issue", I would agree with a go-slow approach---after all, the new GIL hasn't even appeared in any actual release yet. It might be a good idea to prominently document the fact that the new GIL has some known performance issues (e.g., possible I/O convoying), but that feedback concerning the performance of real-world applications is desired.
