With the PEP 370 approach, you can just designate a folder the core
one and symlink all other versions to it. Or better yet, use version
control to push updates to each folder.

With all of the versions sharing one folder, as you'd prefer, it would
be a lot more difficult to actually achieve version-level granularity
if and when you need it. It's not WRONG, it's just providing a level
of control that you don't need at this point.
