Luckily, other browser manufacturers (Mozilla, Vivaldi, Brave, and even the WWWC) have already spoken out against this proposal. Google loves marketing it as ‘optional’, which it obviously won’t be once implemented. A system like this would be very dangerous for smaller browsers, as it’s incredibly vague who decides what authorities would be allowed to verify browsers.

Additionally, this is presented as a way to remove captchas from the web by proving a request is coming from genuine hardware. However, this proves absolutely nothing about a request being genuine or non-spam. The only thing this proves is that it was created by a ‘genuine device’, so all a malicious user would have to do is to (automatically) send the request via a verified device and they’d pass the check.
