We really need them properly attributed on the front-end, I think you're
regressing things here. This should include (or happen after) a change that
takes care of propagating frame through these on the front-end.

It is possible to reconstruct the frame from sendRequest on the client side.

   DocumentLoader* loader = frame->loader().documentLoader();
   InspectorInstrumentation::didReceiveResourceResponse(
       frame, identifier, loader, response, resource());
