I skimmed the bug report comments but didn't find an answer to this:
Why not just monkey-patch?
As far as I know, one can only use normal Python code to monkey patch
modules written in Python. Even then, one can only rebind names stored
in writable dicts -- the module dict and class attribute dicts. The
attributes of function code objects are readonly. Replacing a code
object is not for the faint of heart.
io.py mostly loads _io compiled from C.
