What is our plans for this KEP in 1.32?

@kannon92 The blocking issue can be fixed by https://github.com/kubernetes/kubernetes/pull/122778 which is still in review.

Ping @smarterclayton @derekwaynecarr @dchen1107 @SergeyKanzhelev

• If we want to make some progresses on this KEP, we may have to find some resources on the review of https://github.com/kubernetes/kubernetes/pull/122778 or make another fix for the known issue.

[kannon92]

I'll bring this up in KEP planning.

If you have difficulties getting reviews, I would suggest adding this PR to the sig-node agenda and/or posting on the sig-node slack.

We have two blockers here if I understand correctly.

• blocker bugfix https://github.com/kubernetes/kubernetes/issues/121349 WIP in : https://github.com/kubernetes/kubernetes/pull/122778
• performance blocker issue fix https://github.com/kubernetes/kubernetes/pull/124297 @christianang

This feature is supposed to replace existing PLEG logic, but it has a track of instability and was also downgraded ... are we going to commit resources to replace existing PLEG logic with this feature? if not, should we not consider to remove it and once we are equipped start over?
