Great point about not focusing on code reduction. GraphQL is such a big change from rest that the primary benefit will be different for each team you ask. Form my perspective in a startup with ~50 developers is this: By providing a clear and powerfull interface you can significantly reduce inter-team communication leading to both higher throughput and faster iteration cycles. From a technical perspective reducing round trips is important, especially on mobile devices and GraphQL makes this trivially easy. These two points I suspect is the primary reason many medium+ sized development teams end up implementing their own bastardised version of GraphQL in their existing rest api. Many people we talk to at http://graph.cool http://graph.cool are interested in deploying a thin GraphQL wrapper on top of their existing api for exactly this reason.
