The use cases for using a proxy become more clear over time. When I originally wrote the proxy code the idea was to use the proxy to proxy both the communication with the backend and measurements. It become increasingly clear that we _only_ want to proxy the communication with the backends. Therefore, there's no point in skipping the resolver lookup step when we use a proxy.
