It makes sense. The goal of that API is to abstract the details of 
how / where the sub-objects are stored. The current implementation
is not that efficient, so I doubt that one would be perceptibly 
faster than the other for a standard ObjectManager (though there 
could be quite a difference in another kind of implementation, for 
example an ObjectManager implemented over a relational table).
