Well, I would agree to keep codecs.open() (if we patch it to reuse
TextIOWrapper and add a note to say that it is kept for backward
compatibiltiy and open() should be preferred in Python 3), but deprecate
StreamReader, StreamWriter and EncodedFile.

As I wrote, codecs.open() is useful in Python 2. But I don't know any
program or library using directly StreamReader or StreamWriter.

I found some projects (ex: twisted-mail, feeds2imap, pyflag, pygsm, ...)
implementing their own Python codec (cool!) and their codec has their
StreamReader and StreamWriter class, but I don't think that these
classes are used.
