Description

The doc of replace-a-response-forwarder-per-method is not very clear.

We cannot directly access the forward_MyService_Checkout_0 variable outside the generated gw file. If we modify the gw file directly, it will break the automatic generation mechanism.

So what's the recommended way to overwrite the default forwarder?

Contributor guide

Research direction
Investigate how to customize the response forwarder in grpc gateway without modifying the generated gateway file. Look into using custom marshalers, interceptors, or alternative configuration options in the gateway runtime.
