Another unnecessary and not working feature (whistles and fakes) which does not increase security at all.

To protect yourself, you need to use not compromised computer.

If your computer has already been compromised (hacker, virus, trojan) then nobody will safe you, because your money will be stolen after the first time when you will enter your wallet encryption password.

If enemy can steal your wallet.dat, then nobody prevents him to steal your password.

This password creates only the illusion of security.

So, I made the conclusion that it's rather a minus to security than a plus.
