Focus-recompose method and "soft corners"

Reading endless discussions about "soft corners" and other focus problems in lens tests, it occurs to me to ask if some of these people might be using the focus-recompose method, which many seem to use by default for everyday work. This can cause focus problems, especially in the corners.

For instance, if you're taking a wide angle picture of an off-center lighthouse, DON'T use the center point to focus on the lighthouse and then recompose! Manually move the focus point to where it should be in the scene, then focus!

There are many articles about this problem (try Google), here is a good one:
