I'm not trolling and I don't know the answer to that last one. But I'm assuming the general consensus is that it wouldn't change anything - a plane would be down and everyone would still be dead. So instead of mandating an expensive overhaul of everything that can feed more data constantly I assume they're probably trying to make some already in place tech fill the gap and it has limits. I am entirely speculating on that though. But when in doubt, something usually comes down to a cost-benefit analysis.
