It's doing object mapping because it is coercing everything into JSON. Looking at the language, you see the usual suspects of strange cyclic objects for representing relations typical of ORMs. These systems tend to struggle when dealing with things like many to many relationships, non-total relations, etc. To give it credit though, I do like that GraphQL forces a firm separation between remote and local data, though I'm sure there are already libraries for GraphQL trampling over that separation.
