I've always been taught that the action screws should not absorb any recoil, which would then also apply to the tang.
Correct. With pillars or not I open the holes to 5/16" for screw shank clearance. If the actions screws are controlling the recoil you have 1/4-28 springs!
If you want a sure accuracy killer allow anything but the lug control the recoil.
