While browser cookie UI has been historically bad even for developers, I don't see how a browser's cookie UI could do what these menus do.
For example, load StackOverflow in Chrome incognito. It has buttons for "Accept all cookies", "Necessary cookies only" and a "Customize" menu that gives you checkboxes for "strictly necessary", "performance", "functionality", and "targeting cookies" all with a lot of links and explanations.
It isn't just a matter of turning off third party cookies.
