And until then, a +1 for MAL's position from me as well. 2.x should be quite conservative about such changes... I concur. And a "me too" post about being conservative by default as well.

I will update the PEP some time today. I think if we take MAL's idea of doing the dict.update() trick and suppress the Py3K warnings then it should be able to keep the warnings (it will require a very specific filter). Otherwise the Py3K warnings will just have to go.
