The thing is there are solid, replicable patterns for optimizing graphql. The way we use GraphQL is to expose "everything" to the frontend folks so they can work closely with design until they have a polished frontend for whatever they're building, then our backend folks look at it in APM in Datadog and figure out where to optimize it. Once we have an optimized query, we ship it. Everyone's aware of the basic optimization patterns we use, and backend is a pretty well-oiled machine.
