I can't speak for other TSOs at other airports, but here - where opt-outs don't go through the WTMD - we could get into trouble if we allowed an opt-out to go through. The reason being is that it would cause that person to be counted twice. It's all a matter of numbers. This is also the reason why different airports with AITs allow passengers through the WTMD with different frequencies. The tally for the AITs have to be at a certain level before passenger traffic can pass through the WTMD. While at some airports "choose your own lane" and alternating lanes is sufficient, at some it's not. That's why you sometimes see a back up of people waiting for their turn at the AIT while the WTMD sits idle.
