Sorry, I misunderstood you. Having separate packages makes much sense for
this scenario, indeed.

I have a small brain and therefore I like simple rules like "Every module
Foo simply re-exports the modules Foo.*". :-) Using the .Core suffix would
make things easy:
* We have an SDLCore package with modules rooted at Multimedia.SDL.Core
(a collector module) with sub-modules Multimedia.SDL.Core.Video, ...
* Same for an SDLImage package at Multimedia.SDL.Image
* SDLTTF at Multimedia.SDL.TTF
A "super collector" module Multimedia.SDL would not be a good idea in this
case, because its export list would depend on the available SDL stuff.

Well, Foreign is a bad example, which has been discussed on this list recently.
When we have versioned packages, Foreign should re-export all the modules below
it, nothing more and nothing less IMHO.
