I remember from the report that the KLM crew said "we are now at Takeoff" and then took off with out a clearance. Not sure what difference it would have made if the had said something different like "we are now at departure". In fact it may have been even less likely that the controller would have picked up on it. However, it does make sense to have everyone use the same terminology regardless of that accident.
Perhaps some more thought on it from the rest of the civilized world.
