In http://bugs.python.org/issue17936, I proposed making tp_subclasses (the internal container implementing object.__subclasses__) a dict. This would make the return order of __subclasses__ completely undefined, while it is right now slightly predictable. I have never seen __subclasses__ actually used in production code, so I'm wondering whether someone might be affected by such a change.
FWIW, when I've used __subclasses__, I've never depended on it having a stable or predictable order. (I find it somewhat difficult to imagine *why* one would do that, but of course that doesn't mean nobody has done it.)
