Fully legal and compliant GDPR cookie warnings are also awful UX and a pain in the ass. This should have been done at the browser level.

Not necessarily.

If you're using cookies for things like shopping carts, you don't need a cookie popup at all.

If you're using cookies to track visitors across sites for advertising purposes, you're the problem, and the cookue popup only documents that.

No. If you act in the spirit of the GDPR you never need to prompt people at all.
