Coroplast undertray question (covering the control arms)

Since Coroplast seems to work well for undertray applications, and since it's flexible, why not make a chin undertray that is long enough to go from the bottom of the front bumper and attach to the aft edges of the control arms?

Most such undertrays end at the leading edge of the control arms, with cutouts to allow lock to lock steering travel of the wheels/tires.

However, given the flexibility of Coroplast, the inboard section of the control arms could be covered, to smoothen airflow as far aft as possible. As the contol arms move up and down with road contour, the Coroplast would flex, but have the smallest possible cutout for the wheels.

Why not?
