@stehessel sure, here it is:

Though there's not enough retention time to go back to an upgrade where annotations would be visible

I guess it would be nice to see this in action. Have you actually tested it once and confirmed the rendering?

Another thought: The metric tracks changes to the underlying k8s version. Is this actually equivalent to the OCP upgrades? Couldn't there be OCP upgrades that don't change the k8s version?
