I am not following what any of that has to do with the Web Bot Auth protocol?

it seems like complaints about Cloudflare's anti-DOS protection services and how they have a monopoly on such, I get that.

I'm not seeing the connection to a protocol for bots/crawlers voluntarily cryptographically signing their http requests, so sites (anyone implementing the protocol not just cloudflare) can use it to authenticate known actors?

I am interested in using it to exempt bots/crawlers I trust/support/have an agreement with from the anti-bot measures I, like many, am being forced to implement to keep our sites up under an enormously increased wave of what is apparently AI-training-motivated repeat crawling. Right now these measures are keeping out bots I don't want to keep out too. I would like to be able to securely identify them to let them in.
