I don't know how difficult it is to get rid of the implicit "return None" or even if it is doable, but if it is, it should, IMHO, be done.

It's been proposed before, and the conclusion was that it would cause more problems than it would solve.

(Essentially it would require returning some object that raised an exception when anything at all was done to it, but such an object would cause debuggers and other introspective code to choke.)
