A problem with doing this is whether this will put any extra burden on
python-dev. It's fine if people want to pull out of the stdlib,
package them, and do that work, but in no way should we have to
maintain version compatibility or worry about backporting fixes once
the package is released.
I would personally rather have an informal package done to completely
avoid these issues. That way no one feels obliged to keep doing this
after every release.
