Enabling Upgrade: derp HTTP header with annotations

[santurini]

I am using a service in my Kubernetes cluster which requires DERP upgrades to establish a connection with the server, otherwise it will fall back to websockets (link).

It would be nice to be able to allow DERP upgrades via annotations the same as it is for websockets, for instance something like this:

annotations:
  projectcontour.io/websocket-routes: "/"
  projectcontour.io/derp-routes: "/"

Is this already implemented? Is it possible in case to implement it? I'm not much an expert, therefore I'm asking.
