I'm no apple fan boy and i know they are proprietary but pentalobe screws don't make it more difficult to repair. Pentalobe screwdrivers are pretty much in most kits. It's never stopped me replacing a screen. In fact everytime you buy a screen you get another screwdriver.

I'm no apple fanboy but pentalobe screwdrivers are pretty much everywhere. Every screen you buy comes with one. I don't think it has ever ever increased the difficulty of a repair for me.
