ReCAPTCHA v3, the version I was referring to in what you quoted, doesn't have an audio CAPTCHA or any kind of fallback option at all, which is part of what makes it so much worse than v2. (The other part is the privacy implications of adding thorough behavioral tracking to every part of a website.)
Curious. Do you have any example of a site using it? I noticed that reCaptcha has become much, much worse recently and I assumed that this must be this v3, but I've never encountered one that would actually have no fallback and prevent me from using the site.
