Put another way, my site is unappealing to bots, and frankly I don't care about bot traffic, because I don't have ads. So I don't feel the need to support this server-side.
Equally Amazon makes money selling goods, not ads. They don't need to know if its human or bot, they just need a credit card. [1] Netflix is subscription based, again doesn't care if its a "trusted device" or not. They want you make sure their content is available not blocked because my TV is "untrusted".
Sure, you'll end up using Chrome to use Google properties. But I don't really see the incentive for the non-ad-based Web to bother implementing this.
[1] it won't move the needle for fraud, fraud is easily done via trusted devices.
Amazon is one of the biggest ad networks on earth. They made $40bn from advertising last year using all the personal data they get from their paying customers.

Oh but they do care very much. Netflix requires DRM in desktop browsers and its own app on mobile platforms. And they launched and ad based plan recently.
It's a mistake to believe that advertising is the main problem and direct payments are the solution. Making a payment takes away more privacy than advertising alone ever could and hands personal data to payment schemes and banks on top of everything.
