acceptable screws

I suppose that's what they mean by "six-lobe".

And I would personally much prefer for everything to be torx rather than Phillips head. Phillips head is designed to let the screw get damaged instead of the screwdriver, whereas torx is designed to reduce the chance of cam-out (and therefore damage to the screw). I'd much rather replace a screwdriver than invent a new way to get out a screw that's been rounded out by repeated cam-outs. Again.
