Hello @HirazawaUi 👋!

I'm reaching out on behalf of the Release Docs team.

A friendly reminder that Docs Freeze is approaching today, at 18:00 PT (less than 8 hours). This documentation PR appears to still be under review. Here's where it currently stands:

• Needs a technical approval from SIG Node and/or SIG API Machinery - @SergeyKanzhelev and @thockin have been pinged
• Comments and concerns from SIG Docs (at this moment) seem resolved
• Needs a lgtm label applied
• Needs an approval label applied

If you wish to include this enhancement in 1.34 but are concerned about meeting the deadline, please consider proactively filing an exception request. Thanks!
