What's next for a future plugin that's even more volatile then the current ones?

Sure, that's up to each author or according to the guidelines for
I don't think nagios-plugins' job is to educate the users about the
fact that running everything as root might be a bad idea.
As long as the INSTALL and/or README contains or refers to _sane_
installation/setup instructions I think the nagios-plugins' authors
have done their jobs. And if some distributions/packagers do not keep
it as sane as upstream did, they are the ones to blame.
If I am logged in as root and run a command as root, I sure as hell do
not want it to change to another uid unless I tell it to! (via either
/etc/nagios/check_XXX.conf or a --user=XXX flag).
Let's privilege separate everything and have all plugins chroot
themselves too while trying to keep them easily audited, no? :)
