@jmartisk @mskacelik I'm surprised we use the service loader for these low level classes? What exactly does it allow?

[jmartisk]

@gsmet The io.smallrye.graphql.client.core package is scheduled to be moved into the MicroProfile API - so we supply our own "implementation" classes this way already. This is to allow users, for example, to build a Field using Field.field() where it will locate (and return) the implementation by itself via the ServiceLoader.

OK, thanks for the clarification :).
