Sorry Victor, I somehow didn't see that message even though I received
it (I probably thought it was a continuation of the python-dev thread
which I've been ignoring).

Unfortunately I don't have time to go back and read the whole thread.
I think I haven't used codecs.StreamReader/Writer myself, and I don't
think I've seen much use of them either (which doesn't mean there
isn't). My gut feeling is that yes, they should eventually go away,
but no, there's no particular hurry, and no, I don't think you should
change codecs.open() to call io.open().

I think the best thing is to campaign (e.g. in docs) for people to
stop using codecs.open/StreamReader/Writer and start deprecating them
formally once we feel that most users have switched. It's possible
that that could happen before 3.3 is released, but I'm kind of
doubtful about that myself.

Sorry again for missing your private emails!
