A secondary goal was to enable a smoother on-ramp from "Zero" to "Getting some value".
Historically, Istio had to really be consumed all-or-nothing for things to work as expected.
In particular, an easy answer to "I just want to have mTLS everywhere, then I can think about adopting the rest of service mesh" was desired.

## Goals

Ztunnel should:

			err := s.dataplane.RemovePodFromMesh(s.ctx, pod)
			log.Debugf("RemovePodFromMesh(%s) returned %v", newPod.Name, err)
			// we ignore errors here as we don't want this event to be retried by the queue.
		} else {
			// If oldpod != ready && newpod != ready, but the ambient annotation was added,
			// then assume this event was generated by the CNI plugin labeling the pod on startup,

  // (whether or not they contain an ingress section) are assumed to affect ingress.
  // If you want to write an egress-only policy, you must explicitly specify policyTypes [ "Egress" ].
  // Likewise, if you want to write a policy that specifies that no egress is allowed,
  // you must specify a policyTypes value that include "Egress" (since such a policy would not include

  //       "key": "runlevel",
  //       "operator": "NotIn",
  //       "values": [
  //         "0",
  //         "1"
  //       ]
  //     }
  //   ]
  // }
  //
  // If instead you want to only run the webhook on any objects whose
  // namespace is associated with the "environment" of "prod" or "staging";
  // you will set the selector as follows:
  // "namespaceSelector": {
  //   "matchExpressions": [

      steward.

10.3. Modified Versions

      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a
      modified version of this License if you rename the license and remove
      any references to the name of the license steward (except to note that

  // operation (because it implements the CSI ControllerPublishVolume()
  // method), and that the Kubernetes attach detach controller should call
  // the attach volume interface which checks the volumeattachment status
  // and waits until the volume is attached before proceeding to mounting.
  // The CSI external-attacher coordinates with CSI volume driver and updates
  // the volumeattachment status when the attach operation is complete.
