@kubernetes/sig-scheduling-leads Do you think we can work on it this release? Or should postpone until the next release?

I took a review and I think we can include it in 1.27.

@Huang-Wei Thanks! I'll take a look and modify KEP this weekend.
Do we need to add the milestone to track this issue as a v1.27 feature? If so, could you? (I don't have permission to add milestone on it.)

Hello @sanposhiho 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 18:00 PDT Thursday 9th February 2023.

This enhancement is targeting for stage alpha for v1.27 (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: v1.27
• 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, it looks like once #3651 merges all the above requirements will be met.

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!
