Anyone have much experience with gRPC? We are using Swagger/jsonschema for our REST APIs and it's quite the nightmare in terms of development cost. IMO, writing schemas in a self-describing "language" like JSON should be a crime; it's too verbose and easy to make mistakes. At run time it gets bad because you need to unmarshal the JSON objects into Python classes which can be too much overhead for large request or response sizes.
