The main drive behind this is to allow us to enable http healthchecks on the `/_status` endpoint. The healthcheck requests are happening directly on the instances without going to the proxy to get the header properly set. In any case, endpoints like `/_status` should be generally accessible by anything without requiring any form of authorization.
