Yes, but as we all know too well, people are surely relying on whatever behavior there is, broken or not.

There's also the fact that code which currently runs under 2.x and 3.x would stop working if codecs.StreamReader/StreamWriter were to go away. Of course, if the codecs interfaces were re-implemented using io module code, the only portability issues would be because of people relying on broken aspects of the existing codecs code - which is unlikely to be all (or even most) of the people using codecs.StreamReader/StreamWriter.
