Comment (by bgamari):

 Would it be reasonable? Perhaps. Would it be easy to implement? I don't
 believe so. You would need to somehow walk the heap looking for references
 to freed interfaces so that they can be GC'd (or make any reference that
 might refer to something in another module weak, which would come at quite
 some cost).
