As far as the firewall setup: if they wouldn't get through the firewall,
then there's already extra configuration for operators that want to make
it available to everyone. Why not also have it listen by default on
localhost as an additional safety measure. Especially since *that's how
it is in all current releases*. There's no benefit to moving away from
the (sane) default of localhost-only.

I didn't consider this as a distro-wide change, I'll look at the
existing policies and see if there are any that cover this.
