Multiple versions is going to be a mess. It is a pathetic workaround for
packages that do not care about backward compatibility (eg: CherryPy-2.x
vs CherryPy-3.x).  Drop support for multiple versions to force package
authors to deal with it.

I applaud the Jinja team for doing this:

     ARMIN: The final version of the Jinja2 Django-inspired template
     engine was just released. It comes with tons of improvements over
     the older Jinja1 engine and breaks backwards compatibility to some
     point over the old Jinja1 engine. It's packaged as a separate
     package so that you can use both right next to each other for an
     easier transition.


This is something the Python community can also learn from the Perl
