Hi, I just saw, that the generated Map Class is never used outside of tests, but it would be the perfect fit for the changed mehods, as its use-case is exactly the same.
Also a useful change to prevent problems with Collection types and their generics parameters (f.e. Map<x, y>). See: https://stackoverflow.com/questions/62823341/openapi-generator-maven-plugin-breaks-old-feign-with-querymap
