In reality, I am not at all sure that a quantum leap in complexity
adds to security at all. Any proper use of old-school group
permissions can give as finely-grained a security policy as you would
like.
The time spent running SELinux in permissive mode to configure could
better be spent looking for holes in the operating system, or helping
patch the many bugs that the speedy Linux development schedule lets
through:

And then we could have real security, and not a false sense of
security generated by heavy-sounding phrases like "mandatory access
controls." :-)
