not mine; I'm all for it

I would lobby against that approach as it has non-light semantics (e.g.,
used to target collection of PA objects, etc.).  OTOH, maybe a group
could be passed to a Scene_Item to instantiate a set of objects.  So,
rather than "inherit from", be "composed by"...

It doesn't; but there's plenty of code that enumerates objects in
groups.  I don't think that we necessarily want that automatically
occurring for scene members.

That may well be.
