Thats such a weird clause to include and is likely just a honeypot. Why even bother allowing unverified browsers to connect, since it invalidates the entire purpose of the trust system? If any bad actor can simply choose to not use the trust system while still having full access, then the system is less than useless for its stated purpose (catch bots/bad faith traffic, ensure no malware) and serves only to decrease the speed and experience of legitimate users.

That opt-out clause won't last a year once it's mandatory in Chromium.
