That ship has sailed. It is now on the end user to protect themselves. These banners are just plain noise. No one is reading them. People will click whatever they need to click to dismiss the dialog. The general computing population does not give a shit, and the ones who do will use privacy-oriented browsers and platforms.
Nothing is written in stone or in stars. Nd there used not to be legislation. And now there's legislation that fights towards user consent, so I don't see how anything has sailed anywhere. It's just a bunch of company code that needs to change, with a quick solution of a multiple-deletion commit as an option in most instances.
