    **Added** `istioctl experimental revision tag` command group. Revision tags act as aliases for
    control plane revisions. Users can label their namespaces with a revision tag rather than pointing them
    directly at a revision and selectively decide the granularity of their namespace labels. This makes it possible
    to perform upgrades with the ease of in-place upgrades while having the safety revision-based upgrades
    under the hood.
