Your DOF is at infinity at anything 4 feet away at f/5.6. The difference between f/11 and f/22 shouldn't bring anything in the distance into "more focus"
Based on hyperfocal distances, yes - but that doesnt account for larger print sizes, closer viewing distances or more scrutiny in personal taste for what is considered acceptably in focus. Also, many (most?) times your foreground is closer than 4 feet away.
I go to f/11-f/16 on a regular basis - images sharpen up really well at these apertures. I've gone to f/22 on occasion and its much more useable than one would expect based on all the diffraction talk on this site, but you can see the effects of it with that small of an aperture.
