// a SNI to H2 proxy - similar with the current multi-net gateway protocol from Istio side.

// This has a dependency on k8s - will auto-update the WorkloadInstance for H2R.
//
// However it does not depend directly on Istio or XDS - the certificates can be mounted or generated with
// krun+pilot-agent.
