This also solves nothing. It's up to the ethics of the company how they chose to group "none" "essential" and "all" and what kind of server-side tracking they do anyway.. It's no harder to do the wrong thing with the current system, but at least the headers would be invisible to the user.

Alternatively: Only allow the website to set cookies if it presents headers with the different options, in a standardized way so the user can chose to pre-set a preference and not be bothered with the cookie nag modal.
