All my backend servers expose JSON based RPC api. It does exactly what was intended. No more no less. Works like a charm. I can hardly imagine why would I want to invest in developing / exposing GraphQL layer. Facebook might have their valid reasons but businesses/clients I deal with are not FB scale and do not really give a flying fuck about what FB does. They just need to solve their own particular problems with good ROI.
