Actually, such artificial restrictions enormously reduce the key-space and really make it a few magnitudes easier to break the passwords by brute force attacks.

The only "good" restriction is to force the users to use a long password, say 15 or 20 characters at least. Not only is it safer, usually it makes it easier to remember it too and avoids automatically the "1234" type of passwords.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
