Good point. The thing I don’t like is when people line up and then slowly trundle down the runway towards the next intersection while waiting for takeoff clearance. This uses up runway unnecessarily. Bring it to a stop and then when cleared release the brakes and do a rolling takeoff (unless an icing runup is required). A rolling takeoff reduces the chances of an engine surge or stall as it ensures the airflow is going the correct way through the engine as it spools up.
