True. I've seen this boarding Qantas in LAX, they have the dimensional gauge mounted on top of a scale. Their agents will use it. Oddly enough, their boarding process doesn't include the pointless unnecessary thrash while passengers and FAs wander around blocking the aisle trying to find a place in the overflowing overhead bins to stow baggage. It's probably just a coincidence.
