It absolutely counts. No matter how much depth of field a lens demostrates,
there is always an optimum plane of  focus, and that's where you want to
place the eyes on a portrait subject. Other kinds of subjects will vary that
practice. But no matter what. Optimum focus should always be practice.

I'm not a believer in "F8 and be there" except in cases of extreme speed
required to get the shot.
