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

[Huang-Wei]

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.)
