I feel that browsers should implement a permissions grant pop-up for when a site attempts to set a cookie with SameSite=none, and the cookie api can be extended to enable explanations to be given by the developer.
This essentially moved the banner into the browser, and will make will make ad networks tell websites to not use SameSite=none, but use SameSite cookies and tell those ad networks behind the scenes. There are plenty of ads now already that are seemingly first party hosted (and go as far as transmitting the ad content through e.g. websockets to avoid adblocker detection).
