Hi @serathius! 1.23 Enhancements team here. Just checking in as we approach enhancements freeze on Thursday 09/09. Here's where this enhancement currently stands:

• KEP file using the latest template has been merged into the k/enhancements repo (PR Open).
• KEP status is marked as implementable
• KEP has a 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 (PR Open).

Looks like for this one we would just need the KEP (#2912) merge by enhancements freeze :)

All good now!

Thanks!
