I assume you mean for 3. to fix PyImport_ImportFrozenModuleObject() and not stop resetting __file__ for _frozen_importlib in importlib.__init__ like we are currently doing. I think you're right that it could wait until 3.5 as it will only be apparent to people who are poking around with importlib._bootstrap -- which people should not be doing -- or are using imp.init_frozen() which isn't even documented anymore.
