Or drivability unaffected.
I'm not sure that's a product you would need to have made in China. In fact it looks extremely simple for just about anybody to make in their garage. I'm kind of shocked nobody has tried this before. It's just a short length of chain with a hook on each side and a nut and bolt welded to it.
It's a super clever idea.
I don't know if it would throw chains or not. The ground pressure is pretty low on tracks. I would be more worried about what it would do to the ride then throwing chains. With a rigid undercarriage CTL I would imagine going over those chains is pretty bumpy unless there's enough of them.
