Sure, that makes sense in a 2002 world where we didn't have importlib and all
the modernization of the import system.  Today, it's not only antiquated, it's
also not necessarily true.  We're already significantly overhauling the import
machinery, so I think it's entirely reasonable to relax this constraint.

See my previous post for a proposal.
