This is going to make a HUGE difference for MG-armed planes. While cannon birds will be able to take advantage of it as well, this is definitely going to benefit MGs more since it no longer requires completely blowing off a part to impact the target's ability to fly and fight (seeing as cannon are already more likely to cause outright component failure as it is).
I can't wait for the first time I see an enemy spiral out of control because the skin of his wing has been all shot to hell.
