Making the widespread surveillance that was previously invisible visible (and annoying) seems like a good move to me.
1. Require websites to be concise and offer a yes/no ONLY.
2. Reverse-lobby browser vendors to turn this into an API.
3. Require everyone to use the API.
Now users can block or accept all requests at once like they can block or accept Notification requests.
It doesn't change the fact that they're tracking me, it just makes me click an "X" or "OK" every damned time I visit some new site to read an article or something.
I could understand your argument if sites were actually removing tracking in order not to annoy users with the popup.
But sites aren't doing that, not in any meaningful number at all. So it's not having any effect on privacy, while annoying basically every internet user ever constantly (before you hunt for an extension to block as many of them as you can).
So I don't see how it's a good move at all, not in practice. It's just annoying, and that's it.
Heck, I'm a reasonably technical user, and I wouldn't have noticed in most cases. Again, invisible. Now I have a negative first impression of a site if it annoys me with cookie banners, and a more positive one if not.
