@yujuhong, were there additional improvements planned for the 1.7 release cycle besides kubernetes/kubernetes#45614? If not I'll go ahead and close this issue and we can open a new issue for 1.8. Thanks!

@calebamiles UPD. There is no necessity to close the issue - just move it to the "next-milestone" if it's not planned for 1.8 anymore.
