I hate cookie banners because UX keep going "We keep getting holes in our analytics!" and blaming me for it. I understand the whole "We want to see at what point people are dropping out of the login process so we can make it easier for them to complete the journey" but it's still fucking annoying when they complain about analytics drops when our users are naturally very privacy focused and I can't control whether they deny cookies or not!
There might be ways of tracking without using cookies, but I'm apparently not allowed to use those because the GA is controlled by someone other than me.
