    In Istio 1.18, this has changed to create a fully rendered Deployment and no longer rely on injection.
    As a result, *Gateways will be updated, via a rolling restart, when their revision changes*.

    Additionally, users using this feature must update their control plane to Istio 1.16.5+ or 1.17.3+ before adopting Istio 1.18.
