Second, I've tried to work twice with Doing-It-Right (i.e., fine-grain) permission systems. Once with apparmor and earlier with SE Linux. With AppArmor, I wanted to set up rules to prevent Skype from reading any except a couple of directories. The sheer number of permissions I had to configure was exhausting and I gave up. Maybe I missed something simple, but that's why I'm not clamoring for the current simple, but coarse-grain permission system to be abandoned.
