Hiya @soltysh, thank you SO MUCH for your PRR review and comments. I did decide today with @tallclair to wait for 1.32 to put this in an actual release because we don't like the API I suggested enough for how complicated it might be to back out of it. Just wanted to take it off your radar on this most auspicious day, 1.31 enhancements freeze ;)

I've updated this PR to be valid as to merge now in a provisional state, without the PRR, and with several UNRESOLVED blocks, so I can separate out the updates to the 1.32 variation so that can be handled in a separate, clean PR for discussion.

/assign @SergeyKanzhelev for approval

FYI to connect the dots for posterity, 1.32 PR (draft right now) is at https://github.com/lauralorenz/enhancements/pull/21

UPDATE: PR into k/k is at https://github.com/kubernetes/enhancements/pull/4893

/lgtm

There are the following unresolved topics:

• Rapid Restart Implementation
• Node-Level Opt-in
• Benchmarking and Stress Testing
• Interaction with Job API
• Kubelet Overhead Analysis

@lauralorenz and @tallclair indicates they are going to be covered in the following KEP PRs for 1.32, which makes this implementable.
