Anyone using the Crawler Hints feature on Cloudflare?

As per their description: Crawler Hints provide high quality data to search engines and other crawlers when sites using Cloudflare change their content. This allows crawlers to precisely time crawling, avoid wasteful crawls, and generally reduce resource consumption on origins and other Internet infrastructure.

Has anyone tried it?

I have tried, it automatically sends your links to Bing and Yandex afaik. And yeah actually my pages indexed on these search engines after enabling.

Has anyone else tried this and did it work with Bing?
