Sure, but the vast majority of websites where I see these cookie prompts aren't even websites I'm logging in to in the first place... often they are websites I am not sure you can even log into at all. I get that if I want some kind of fine-grained cookie handling for websites that are legitimately using cookies for something I need to rely on them, but that initial "do I want this site to get cookies at all?" is almost always "no" and I should not have to rely on them for it.
