Nope, I've never had a "direct mount" side pull brake of any kind. I've got older 105, Ultegra and Dura Ace dual pivots with either nutted or recessed nut mounting. These all date from 2005 or earlier and that was well before direct mount calipers were even though of. As I mentioned you can set the pad gap by adjusting the cable length, center them by hand and then tighten the mounting bolt/nut to keep them from moving off center. It's never failed.
The only brakes I've needed the centering screws for were V-brakes and cantilevers and those just controlled the return spring tension.
