With 10,000 nodes running kube-proxy it is a bit expensive and, more importantly: error prone. A problem on a single node that wasn't even talking to the app could stop that app from exiting indefinitely if acks were required and clusters this size already do gigabits of traffic in endpoints watches.

Additionally, there's no acks possible for clients of headless services, so just kube-proxy handling this doesn't go far enough.

But yeah, maybe accept that as a tradeoff for clusterip services, but more deeply integrate the real load balancer options.
