Not a true greentext but I hope I have captured the spirit of it. (First time I wrote smth like this, don’t be harsh on me. >w<)
Websites need desperately to display their password creation rules on login pages. If I knew this particular site had (for some dumbass reason) a maximum password length less than the length of the password I’d otherwise use on that site or (also completely unreasonably) restricts special characters, I can more easily figure out what password I used when I signed up with fewer wrong guesses, all without sacrificing any security. (It’s not like the rules aren’t public info that anyone can get. Just don’t make me go halfway through the signup process to get that information if I’m just trying to log in.)
It would also let hackers know what combinations not to try.
I have a better proposal: If your login page has any restriction on passwords (other than being part of Unicode and a max length of 128 characters) then your site should be shut down.
