Hello @mimowo 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on [02:00 UTC Friday 9th February 2024 / 18:00 PDT Thursday 8th February 2024](https://everytimezone.com/s/1ade3dca):.

This enhancement is targeting for stage beta for v1.30 (correct me, if otherwise)

Here's where this enhancement currently stands:

• KEP readme using the [latest template](https://github.com/kubernetes/enhancements/tree/master/keps/NNNN-kep-template) has been merged into the k/enhancements repo.
• KEP status is marked as implementable for latest-milestone: 1.30. 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](https://github.com/kubernetes/community/blob/master/sig-architecture/production-readiness.md#submitting-a-kep-for-production-readiness-approval)).

For this KEP, we would just need to update the following:

• KEP status is marked as implementable for latest-milestone: 1.30.

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