I’ve been thinking that it could be a great safety feature. If every site had its own mapping then uses a hash it would eliminate simple password matching. If they get access to the database, you could find the password by taking common paswords hash them and do a match. This would not be impossible with the speed of databases. If every site did that it could prevent this line of attack. I can’t really see a bad thing about.
