> User agents should have the ability to convey and enforce privacy preferences on behalf of the user, and website providers should be legally required to comply with these if possible (or refuse service if not).
The burden of respecting privacy choices in every single other case (data in the backend, data shared with partner, paper data) is already with the website. Every non-privacy-respecting implementation in the frontend is made by website owners.
Keep in mind that sometimes websites don't work with blocking other stuff, or are more difficult to use when blocking fonts (Google Material). So this is not even a practical suggestion.
