We need to handle the media URLRequestContext, app URLRequestContexts, and channel ID, at least. There's also cert verification. I suppose the extensions URLRequestContext is a bit tangential, and there are separate bugs for domain reliability, NetLog, and the DRP. There's also the network error logging service. NetLog has its own bug, I think.
