LOL no, we're using websockets but doing REST-like requests over it. It's fun!

Sounds like you're making it hard for yourselves on purpose. May I ask why you (the team) chose this over other technology and what was the decision process at the start the project?

Do you think GraphQL has contributed to more microservice driven development?

Yes, not in a bad way. I love graphql to be honest. Federation (using Apollo) is awesome.
