In the case of base64.py, it simply doesn't use those differences.  In
the case of creating a "UsercStringIO" wrapper, the additional
functionality could be cheaply implemented by the wrapper.  Or, the
additional stuff could simply be added to cStringIO.

Absolutely.  I would not propose breaking backward compatibility.
