If Falcon 1 is to be thrown into the ring for consideration due to engine similarity, then we'd have to figure out where Vulcan fits. It already flew the same kind of engines that powered New Glenn.

Just a thought.

Very fair point. In some ways that would make NG a more iterative approach, but Vulcan is another example of, at least mostly, a waterfall approach.
