Jeez, wrong on both counts. No-one needs to replace /bin/login, simply print a message to the screen saying "Linux blah \n login:" and then wait for someone to take the bait.
Secondly, NT's C-A-D requirement DOES prevent this, and thus DOES add security, AND to make things better, I don't see how it makes life any harder for users - it's just some keys you press to get a login screen.
