No. It's you solving your problem with gnome-user-share and declaring
the fallout somebody elses problem so you can safely ignore it.

The fact that the current GUI (and zone naming) sucks big time doesn't
imply that the underlying concept is unusable. The big advantage of
using firewall zones is that it works outside the gnome universe too.
(1) Pulling the qemu/kvm vnc server example again, which you decided to
not respond to last time I mentioned it. I want the guests vnc
display be reachable in my home networks and not reachable in
public networks. Doing it with the firewall works.
(2) Heck, even the gnome-user-share UI shows that. Pick "Remote
Login", notice that you can NOT select networks for sharing.
Yes, I know why you can't pick networks for ssh. But this IMO clearly
shows that the "just don't listen on untrusted networks" as distro-wide
policy isn't going to fly.
