It may make sense to target a particular set of primitives. However, that isn’t much of a help when you need an object that isn’t in the list of primitives. A general composition mechanism is still important.

Of course another approach is to recognize common compositional idioms when exporting. This may have the advantage of not favoring any particular kind of exported product.
