You wouldn't want to remove unused holds, because in the future, someone may find a more efficient path the makes use of that hold, but ignores other ones.
Sometimes climber, but not a speed climber: it would be vanishingly unlikely for a hold that far left of the button to end up on a more efficient route. Closer to the middle of the route, maybe, but it'd be a sharp jog to the right to hit the button from having any appendage on that hold.
