Yes, with the revised proposal, only the module level functions would
change their behaviour to use a CSPRNG by default. If you trawl the
various cryptographically unsound password generation recipes, they're
almost all using the module level functions, so changing the meaning
of random.Random itself would add a lot of additional pain for next to
no gain.

Nick.
