Whatever you hit off-center, goes out with less than optimal pace and an undesired launch angle. Hitting of center on purpose can only be done close to the sweetspot where the outcomes are reduced, or by risking to increase the % of hitting the frame and losing punch in every shot.
A racquet shaped like that can bring other benefits though. The axis of minium inertia are shifted and can enhance some mechanical aspects of the swing that are beneficial for the game. To what extent I don't know.
