* The Gateway Deployment controller enables users to create a Gateway which actually provisions the underlying resources for the implementation (Deployment and Service). This is more like a traditional "operator". Part of this logic is determining which Istiod revision should handle the resource based on `istio.io/rev` labeling (mirroring sidecar injection); as a result, this takes a dependency on the "Tag Watcher" controller.
