Something sounds a bit fishy if your arab was really bad undersaddle and suddenly you shove a chain bit in his mouth and he's perfect? Chances are it was so harsh that yes, it definitely prevented him from acting up. If that's the shortcut of training you wanted to take, who am I to stop you? That's your choice, your horse.
He for 12 years of his life was ridden in a TT (before we bought him) by kids at an inner city camp. He flunked out because he became dangerous. Regular snaffles didnt do it an at the time I didnt have a frenchlink. Tried the chain bit an he suddenly didnt hate having a bit in his mouth , cues were suddenly understandable for him.

And I disagree with your statement that the bit would have to be sharp or distorted to cause injury. Long before I owned my gelding, when he was roughly a year and a half, the barn owner had the bright idea to lunge him. Since he was headstrong she threw a liver pool driving bit on him.

And then aggressively lunged him for 20 minutes. I arrived at that time, saw what the hell she was doing, came up with an excuse and offered to untack him and take him inside for her. Once alone in the barn, I carefully took that bit off and his mouth was bloody. Thankfully no teeth had been broken, but his bars were rubbed raw, his mouth was sore and from then on he'd panic and freak out if he so much as saw a bridle.
OK, rambled alittle there but my point was - his mouth got bloody off a "simple" straight bar, so I don't need a creative imagination to figure out the chain issue.
ANY bit can do that. All you proved was what matters most is the hands that the bit is in.
As for the liverpool , they commonly have a serrated edge that rests against the bars/tongue. The straight up an down shanks are also a detrimental factor.

Maybe you should run a thin chain over your tongue for an hour, then come back and tell us it's not cut or even sore. image
Maybe you should be better educated about the mechanics of bits an there uses before speaking.
Once again your speaking out of context. Nowhere did she say she did for an hour.
