    **Added** experimental support for controlling service endpoint discoverability with Kubernetes Multi-Cluster
    Services (MCS). This feature is off by default, but can be enabled by setting the
    `ENABLE_MCS_SERVICE_DISCOVERY` flag in Istio. When enabled, Istio will make service endpoints
    only discoverable from within the same cluster by default. To make the service endpoints within a cluster
