Donˋt know what is the fuzz about. The Cirrus is a low wing airplane with maximum height of 2.73m which is the tail. The SR22 Pilot taxiing has a perfect visibility to all relevant parts of his plane. A320 wing clearance on the outside is 4m. The danger and responsibility to run into something expensive is sole with the Cirrus pilot. So unless he tries to pass under the body or engines of the A320, nothing will happen. The prop blast of the Cirrus at taxi speed will not blow away the A320. So what is the problem here?
