No, selinux is a *royal* pain. It may be good for a production box that
has systems tested to within an inch of their lives, and you go through an
approval process... but for anything else, most folks put it into
permissive mode. Certainly, we do, given that there are some AVC's I've
been trying to figure out for *months*, and still don't know how to fix,
or where the files are that it's complaining about; or want to allow this,
but not everything, and have no clue how to allow *only* that, etc.

You mean like the std. upstream practice of creating, by default, a new
group for EVERY BLOODY USER, and not, by default, dumping them into, say,
users?
