Is there any reason that codecs.open() can't become a thin wrapper
around builtin open in 3.3?

How API compatible is TextIOWrapper with StreamReader/StreamWriter?
How hard would it to be change them to be adapters over the main IO
machinery rather than independent classes?
Rather than deprecating them, that seems like a more profitable
direction to take them.
