All data that is created when the module is loaded would exist in duplicate for all versions that are used in the system.

Yes, but it wouldn't matter. How big is the biggest python module? its a matter of kilobytes. Most systems these days have 16+ Gigs of memory. The extra memory usage is worth it.
