Well, why didn't the password managers in several browsers do that by default?
Also, not all attacks are about "pwning" a computer. If an attacker can gather data, such as competitive corporate data, without being detected, that is much better in many ways. In practical terms, it would also be much faster (and unntraceable) to look at 2-3 key passwords in someone's open Firefox than to infect their computer with malware.
