Hello @knight42 👋, 1.25 Enhancements team here.

Just checking in as we approach enhancements freeze on 18:00 PST on Thursday June 16, 2022.

For note, This enhancement is targeting for stage alpha for 1.25 (correct me, if otherwise)

Here's where this enhancement currently stands:

• KEP status is marked as implementable
• KEP has a updated detailed test plan section filled out
• KEP has up to date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements.

Looks like for this one, we would need to get the open KEP PR #3289 merged by Enhancements Freeze:

For note, the status of this enhancement is marked as at risk. Thanks for keeping the issue description up-to-date!

[Priyankasaggu11929]

With KEP PR #3289 merged, this enhancement is ready for the upcoming enhancements freeze.
