Anytime you have an extra piece of rope or cord attached to the back of your tank, it is an entanglement hazard. It might break away eventually, but not before it's managed to drag a ball of monofilament or fishing line into your tank valve. Or maybe you want to drag around a big ball of kelp or seaweed.
Secondly, it's NOT a redundant form of communication. It would only be redundant if there was no other way of making a 'bang' on your tank. I don't dive with any danglies whatsoever, but I still have three or four things I can bang against my tank - not that I ever would.
And if your "attention is wandering" all you've managed to do is make a noise. It's non-directional - your lost buddy still can't find you because of it.
Tank bangers are an accessory designed to be sold to stupid divers.
