I feel that I need to do some research and testing to understand this completely. But I agree that running kube-proxy on the apiserver feels strange. Feels that the implementation of metrics-server could be different.

I managed to get the metrics-server up and running. I got a bit of help in the avove issue.
Short summary: To use APIService extensions to the API server when you are not running kube-proxy on your master nodes, you must set the flag --enable-aggregator-routing=true on kube-apiserver. This effectively means that the API server won't use the service IP's to reach the APIService. It will instead use one of the endpoints of the service. Now, this won't work out of the box either, because the API server cannot reach Pod IP's either. But if you set metrics-server (or whatever extension you are adding) to use hostNetwork: true, it will work (of course with the downside of using hostNetwork, but I think I can live with that).
