That is funny because on this page there is a warning block with the following text:

   Refer to Will Browser Rendering bypass Cloudflare's Bot Protection? for instructions on creating a WAF skip rule.

Is it because it was removed (/hidden) or because it is not yet available until everyone forget the "we are no evil, we are here to protect the internet"?

most websites, particularly those behind cloudflare, are very restrictive even to crawlers that obey robots. Proof: a ton of my time over the last year, and my crawlers very carefully obey robots.

It's hard to see how this isn't extorting folks by offering a working solution that, oh, cloudflare doesn't block. As long as you pay Cloudflare.

Perhaps I'm overly cynical, but I'd be quite surprised if cloudflare subjected their own headless browsing to the same rules the rest of the internet gets.
