Apple already shipped attestation on the web, and we barely noticed

Maybe I'm wrong but Web Attestation will also be a death knell for Linux devices (not Android/Chrome OS) as far as being able to use them as equal clients to use the Web goes. They're simply too diverse and 'hackable' as a plotform for remote attestation to work reliably and thus they'll be excluded altogether (except a few 'blessed' distros that will then become industry controlled, and not Linux in spirit anymore).

So far, Private Access Tokens are not widely adopted so you can get a feel for the potential Linux experience by browsing the web with iCloud Private Relay enabled. This flags almost every website's anti-spam classifiers, and you end up having to do 3-5 captchas to access anything protected by one.
