GraphQL might work OK though, because it differentiates queries from mutations - so you could have some early logic that says "if this POST request includes a mutation, replay against the leader - otherwise keep running against the replica".
It's true! We designed this specifically because it works with GraphQL. The exception->replay works by default, and it's easy to send early replay command on GraphQL mutations.
What is more you could just have your client send all mutations to one API and all queries to another. I suppose you could do that with REST as well by in Graphql the deliniation is very clear and there are only 2 cases you need to handle.

Cries in GraphQL (where you generally POST, even for queries).

A standard QUERY verb should fix this.
