Quite agree, DEB'E.
Imagine the situation if there was a video referee judging whether there was a "foul" on Aguero or not. This review can be taken while the players are arguing with the referee over the incident, and will not take up any further time.
"Should that have been a penalty, Mr Webb, Mr Jones?" "No, the defender just about touched the ball, not enough to change it's direction, and the contact with Aguero was merely incidental. No penalty" says Mr Webb. "Despite the fact the defender didn't touch the ball, and the incident was in the penalty area, it was obvious that Aguero dived . No penalty, and a yellow card for simulation to Aguero, " says Mr Jones.
Sums it up, really.
