Think about security for a moment. On the one hand, you want your website
to not reveal whether usernames are already taken, so when people log in
you will want to say "username or password incorrect". However, you also want
to be able to tell people that they can't register because the username they
picked is already taken.
Because these are mutually exclusive, you can't do both using this framework.
You can either use unsafe reporting, where the system will will tell you that
a username exists, both during registration and login, or you can use safe
reporting, and then the system will reject registrations based on username
similarity, not exact match. But then it also won't say which of the username
or password in a login attempt was incorrect.
