Hello @wojtek-t 👋, 1.31 Enhancements team here.

Just checking in as we approach enhancements freeze on on 02:00 UTC Friday 14th June 2024 / 19:00 PDT Thursday 13th June 2024.

This enhancement is targeting for stage beta for 1.31 (correct me, if otherwise)
/stage beta

Here's where this enhancement currently stands:

• KEP readme using the latest template has been merged into the k/enhancements repo.
• KEP status is marked as implementable for latest-milestone: v1.31. KEPs targeting stable will need to be marked as implemented after code PRs are merged and the feature gates are removed.
• KEP readme has up-to-date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements. (For more information on the PRR process, check here). If your production readiness review is not completed yet, please make sure to fill the production readiness questionnaire in your KEP by the PRR Freeze deadline so that the PRR team has enough time to review your KEP.

With all the KEP requirements in place and merged into k/enhancements, this enhancement is all good for the upcoming enhancements freeze. 🚀

The status of this enhancement is marked as tracked for enhancement freeze. Please keep the issue description up-to-date with appropriate stages as well. Thank you!
