Hello @Jefftree 👋, v1.34 Enhancements team here.

Just checking in as we approach Enhancements Freeze on 21:00 UTC Friday 20th June 2025. (That's tomorrow)

This enhancement is targeting stage alpha for v1.34 (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: v1.34.
• 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.

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

• PRR completed and merged

The status of this enhancement is marked as At risk for enhancements 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!
