Hello @HirazawaUi 👋, Enhancements team here.

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

This enhancement is targeting stage alpha for v1.31 (correct me, if otherwise)

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 before the enhancements freeze.

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

• Retitle and attach the PR in this KEP description for Alpha
• Update the KEP status as implementable once reviewed.
• PR needs to be reviewed and merged within the mentioned timeline.

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.

If you anticipate missing enhancements freeze, you can file an exception request in advance. Thank you!

To opt in, let us know and open a Feature Blog placeholder PR against the website repository by 3rd July, 2024. For more information about writing a blog see the blog contribution guidelines.

Note: In your placeholder PR, use XX characters for the blog date in the front matter and file name. We will work with you on updating the PR with the publication date once we have a final number of feature blogs for this release.
