Try it. If it works for you, then use it and ignore other people.
I think that the main problem people have with the method, is that it's fairly easy to get your focus messed up, depending on how far you move the camera. For example -- you focus on something with the center point, and then move by rotating your body -- now the lens has focused at a certain distance, and the camera has moved slightly farther away from your subject due to your rotation. Whether this actually
matters or not depends on many things, such as your aperture.
So, give it a try. If your photos end up slightly out of focus, it's probably because the method is a little too imprecise for what you need. But, I use this very frequently, and rarely have trouble. It just takes some practice.
