I have thought about the slotted screw heads myself. I figure it one of two ways or maybe both. It's cheaper to make slotted screw heads and the slotted screw heads keep the assemblers from over doing the torque and snapping them off. I'm working on a build with a vintage feeling so I am willingly keeping the slotted heads. I've had the covers off and on and it seams a proper fitting screw driver blade works wonders. They are tight but a good fitting large screw driver does back them out. I can only speak for myself.
