That whole lazy loading thing looks finicky to me. Personally, I'd
rather just deprecate the old behavior of bringing everything into
scope on import, but `vtkmodules` is a good middleground.

This would be `from vtkmodules.vtkSomeModule import vtkSomeFactory`. The
point of vtkmodules is that the top-level package *doesn't* import
everything.
