Soon all cookies will be treated with SameSite=Lax policy, unless website specifies otherwise. That means that by default it won't be possible to track users on other websites. It's still possible to track users with cookies using SameSite=None, but it's expected that most cookies should not use this setting, so browsers theoretically could use an approach similar to allowing notifications or location services: ask user for permission before accepting that cookie.

So if that UI will be deployed, may be those popups won't make sense anymore.
