I must be missing something, what about these options is new? With any API gateway solution, you should be able to implement blue/green deployments or feature flagging. With GraphQL it is very much still possible, but with RESTful endpoints, much of this was actually easier: you could blue/green deploy or feature flag individual endpoints. With GraphQL, each service’s entire graph gets deployed together.

To be fair, I love GraphQL and use it extensively, I just wonder if it’s given a little too much credit sometimes.
