Even though they tasted great, I doubt I would ever buy them, or the beef ribeyes either. They are very cool to look at but the big bone adds nothing (but the coolness) and probably adds considerably to the cost of the cut.
Yeah, it's just a pork chop with the side flap removed. And you're going to pay more than double for a butcher to remove when you can do it yourself (but why would you because that is where the fat and some of the best meat is?).
