Have been messing around in sailboats for more than a half century. When I started sailing the rigid vangs weren't around. Strangely, we still used vangs. They were tackle attached to the boom and the tack that you'd call soft vang today.
The rigid vangs are great as a set and forget boom control device that will also support the boom. Seems that a bit before the rigid vangs became de riguer somebody invented a high tech device called a topping lift
