The template for this section says it is only required when targeting beta to a release. I would expect for beta we would add a metric to capture the total time used for ratcheting, but did not think it needed to be explicitly part of the KEP yet

Specifically the 5% cost metric would be against the total time for a request during a write, so apiserver_request_duration_seconds

non-blocking

The idea here is that operators want to see if their users are making using of the feature. It helps them know two things: 1) is anyone using the feature, or is it safe to turn it off; 2) if no one is using it, then it can't be (or is unlikely to be) the source of some production issue (e.g., during troubleshooting)

Thank you for the clarification. We likely will add a metric to measure the total time taken for the comparison in a later release.

A metric that shows when ratcheting takes place in writes would be helpful here.
