Your mistake is thinking a login is a person and a person has an email. I have run into all three of these scenarios: 1) A login for an administrator area on a server has a different login/password than the main area, and the browser always fills in the main login/password, even though I ask it not to. autocomplete=off would fix this. 2) A new user and edit user screens exist in web apps that are driven by users sign-ups. Sometimes these things need to be coordinated with other systems in a corporation and users do not always have their own email (I know this is a shock for you, but it is very common). autocomplete=off would fix this. 3) Using a remote admin tool to setup a datasource on a server, the username and password fields refer to database credentials, not a person. Yet Chrome keeps filling in my info. autocomplete=off would fix this.
