The rear wheels can push directly on the frame when connected, instead of the sheet metal floor being part of the 'push'.
As the rear frame rails are solidly welded to the rear of the body assembly, the leaf spring bushings are the component that absorb the forces of road vibration and drivetrain action. The subframe connectors do very little, if anything, to affect the rear suspension. What they do is help prevent the body from twisting, or in the case of convertibles, sagging as well.
