Yes if my goal was to have anyone who uses an SELinux system, to totally 
understand the difference, but my goal is to have the largest possible 
segment of computer users gain some protection for SELinux.  Forcing 
them to label every package in the world correctly or blowing up the 
application for very little increased security is just nuts.

Right now I have SELinux usage in Fedora at > 70%  If I turned off 
unconfined_t and unconfined initrc_t and started preventing execution of 
usr_t, I would bet that number would collapse.
