I'm guessing the reason we want attestation is so that Chrome can drop ad blockers and websites can drop non-Chrome browsers. But there is no reason why you can't do the thing where you point a video camera at a monitor, have AI black out the ads, and then view the edited video feed instead of the real one.
The only use for attestation I see is for work-from-home corporate Intranets. Sure, make sure that OS is up to date before you're willing to send High-Value Intellectual Property to the laptop. That... already works and doesn't involve web standards. (At my current job, I'm in the hilarious position where all of our source code is open-source and anyone on Earth can edit it, but I have to use a trusted computer to do things like anti-discrimination training. It's like opsec backwards. But, the attestation works fine, no new tech needed.)
Is this truely going to work though? Captcha provider already monitor mouse and keyboard movement while on the page. Can you really "synthesize" human-like mouse movements around the page? I'm not so sure.
Yes. It's not even very hard.

You're behind the times. It's not widespread but it's been happening for years.
Also the other day selenium author (iirc) said they are working on such a thing for "automated testing"
So this proposal will do nothing to prevent bots; maybe increase the cost a little.
On the other hand, it will surely discriminate people, new emerging technology and companies. No other search engines can be built. No new browsers. No openness.
Anyone supporting this proposal is either pure evil or stupid or both.
