Reading of a value may not be a big deal, but giving write( ability to change the setup ) access of such a device to a regular user is a very bad idea. Or would you allow a regular user have such access to say, /dev/mem too ? If there ever was a perfect use for setuid / setgid, and / or IPC, I'd think this would be it. However if these "many people" who find such things diffficult should spend more time reading about the OS they're trying to use.
