It'd be a nice feature for sure. However these cars have so much power that if you slowly let the clutch engage it won't roll backward, nor will it stall. It'll very slowly start to creep forward and you just give it gas.
However, this feature would be great if it works for reverse. For whatever reason, my clutch hates it when I back up a steep hill. If you feather it at all you're rewarded with a great burning clutch smell.
