Having more implementations of GraphQL APIs for various backends is tremendously useful for data integration using schema stitching / federation / remote schemas. And even without that it provides a uniform way to address many types of data stores.
Also the term 'retrofit' is a bit odd for an API, as there is no canonical backend, so there are only retrofits in that sense.
