Move to Ambient and EnvoyFilter Goes Silently Ignored — The Gap Istio 1.30's TrafficExtension Closes, and What It Doesn't
The real obstacle blocking migration to ambient mode isn't resources — it's extensibility. Istio's official migration doc states outright that EnvoyFilter is not supported on waypoints, that it will be "silently ignored"
