I would like this, for the same reason I have my firefox set to do the same thing when I close the window with multiple tabs. It's convenient, and even if you only end up having to really use this feature once in your elements career, that's one time it saved you, and lord knows other people have more problems then XP I've done this a few times where I attempt to click on a tab, but I move my mouse over too far and it accidentally hits the little "x".
