Before stop/start came along, I was in the habit of just holding the clutch pedal down while stopped at intersections or in traffic. Anecdotally, I think most drivers do the same.

I usually keep my foot to the side, as I was explicitly taught in driving school by a professional instructor to do. And if the master cylinder ever starts to malfunction, since the plate spacing is really tight, keeping the clutch pedal depressed while stopped could prematurely burn up the clutch and the torque plate.

Its called 'riding the clutch'. But all you have to do to avoid the wear is keep it fully depressed. End of moralizing.
