It's in the packaging guidelines that server applications shouldn't auto-start.
It's not like I'm making this up...

I'm so sorry for missing one line in the 200+ emails from the thread. The firewall
is still there. You can still use it. Which is better than what happens in F20 and
before: 1a) developers disable the firewall because they have better things to do
1b) they switch distributions (when possible) because they have better things to do
2) they can't apply firewall rules to the VMs because the firewall is disabled

You found a use for the firewall that's still running.

This isn't gnome-user-share. It's the sharing panel in the control-center. And it's
not there because I wasn't sure whether changing the status quo for this was
1) necessary 2) how to implement it without breaking the setup for administrators if
the user can choose to enable/disable the SSH server themselves.

I don't see how keeping the status quo for one (system-wide) service necessarily
 invalidates the design decisions done for all the other (user-wide) services.

I'll implement that if it's all it takes for you to admit that, yes, it's actually
going to fly.
