Hello @atiratree 👋, 1.31 Enhancements team here.

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

This enhancement is targeting for stage alpha for 1.31 (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).

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

• Create the KEP readme using the latest template and merge it in the k/enhancements repo.
• Ensure that the KEP has undergone a production readiness review and has been merged into k/enhancements.

It looks like https://github.com/kubernetes/enhancements/pull/4565 will address most of these issues.

• [ ] Get https://github.com/kubernetes/enhancements/pull/4565 merged before the enhancements freeze.

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!

This and https://github.com/kubernetes/enhancements/issues/4212 where discussed heavily again during Monday's SIG-Apps call, with the general hesitation from SIG leads we're going to hold on with these efforts in favor of looking into extending PDB and eviction API.
