Exactly! Once its working, it can be very healthy. And especially on the client. For a very, very, very long time. We started using GraphQL at the very beginning, back in 2015, and the way it has scaled over time -- across backend and frontend -- has worked amazingly well. Going on 10 years now and no slowing down.
We haven't been using it as long but it's definitely saved us from things that were "impossible" to associate in our microservice backend.
