Privacy Pass: why bother?

Finally decided to post about it…

What good is Privacy Pass Using Privacy Pass with Cloudflare – Cloudflare Help Center if you have passes but the captcha page is still shown to you anyway?

My understanding is that privacy pass will re-use a captcha result to authenticate to more pages without filling out as many captchas. It does not remove them entirely.

When an internet challenge is solved correctly by a user, Privacy Pass will generate a number of random nonces that will be used as tokens.
