While historically the cookie warnings were only an annoyance these days they often have a (working!) option to reject cookies, giving those popups at least some purpose.

Really though setting cookies isn't the problem, and you don't even need to show a popup according to EU law. You only need that popup if you use the cookies for nefarious things such as sending tracking information to ad networks. Setting a cookie for functional things such as remembering logins has always been allowed without a giant-ass disclaimer and nothing has changed in that regard.
