Definitely -- my plan is to provide the spectrum of choices and also
have accompanying explanatory text so that users can make an informed
decision about what they want to use SELinux-wise on their system

Yep, and hopefully then in the longer term, we can move to more and more
locked down setups as users become used to the concepts introduced by
SELinux and applications become aware of it.
