I totally see the appeal on the surface level of a nicer/cleaner looking query language and API. Still, pretty much everything else you mentioned seems doable with REST. I'm using Marshmallow schemas in Python which seem to act in a similar way on a field by field basis as a GraphQL resolver does. I'm not sure what exactly I'd be getting outside of a slightly nicer/cleaner abstraction by moving to GraphQL, but maybe that's enough?
