It seems to me that GraphQL could be awesome when you exclusively control the back-end and the front-end, but do you think it will work as well if you're building an API that also needs to support third-party clients? Would REST still be better in that scenario?

Edit: I see that they partially address this: "Many of these attributes are linked to the fact that “REST is intended for long-lived network-based applications that span multiple organizations” according to its inventor. This is not a requirement for APIs that serve a client app built within the same organization."

That's a great point. We definitely have designed it for first party clients in mind. This doesn't preclude use cases in the future, but for the short term, this is a nongoal.
