The interface definitely should be implemented at the browser level.
If a user sets "allow performance telemetry, deny fingerprinting, ads, tracking" or "decline everything non-vital" once in the browser settings, he should never see a cookie banner ever again - with all of that communicated to the websites by the browser for him, and the websites being obligated to respect the user preferences.
The cookie banner vomit should be reserved only for browsers that don't support that. The fact that this obnoxious behavior somehow became the Internet's default is an atrocity.
