But how often does your persistence model really reflect the domain model that accurately? In going from domain to relational at least, you pick up a lot of details that are key to relational modeling but are irrelevant to the domain model, as in the indexing here.

As best I can tell from my limited experience, GraphQL is just exposing the bones of your relational schema without giving it much domain behavior. It's the software equivalent of offering a grocery store full of ingredients when all the hungry person wants is a sandwich.
