Hello @alexzielenski 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 01:00 UTC Friday, 16th June 2023.

This enhancement is targeting for stage alpha for v1.28 (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: v1.28
• KEP readme has a updated detailed test plan section filled out
• KEP readme has up to date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements.

For this KEP, we would just need to update the following:
-Fill out questions on e2e test,Rollout, Upgrade and Rollback Planning, monitoring requirements.
-Ensure the Pr is merged

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