I can't speak for everyone, but there is no way I would sink with an A-10 on. The vest provides enough flotation to make it easy to stabilize yourself while waiting for the boat to pull you up. And it provides a degree of impact protection. I don't know of any vest that will keep your mouth and nose out of the water if you are knocked out. I won't discount the possibility that some people are natural sinkers, so maybe it isn't appropriate for them.
