Come on, don't reject it so flippantly. Sure, for the case of a woman getting married and taking a new last name, I doubt it's that big of a deal - you can change your name for future commits, but your old name will exist for historical commits. However, there _are_ cases where you might not want your former name around (transgender, or even something like privacy / witness protection). Right now, these folk are being sort of excluded (however inadvertently) and it's worth discussing ways to fix that.
