Fedora 21 and its Workstation firewall

Then what's wrong with setting the zone to "home" in NetworkManager for your home wifi? And open ports, even all, in firewalld for the zone. Doesn't this give you the exact functionality without stripping the firewall when you're somewhere else? I certainly don't don't always remember to go through all running applications and services before connecting to a coffee shop wifi. I prefer the computer do these kind of mindless things by itself.

I've never had any problem printing to a network printer or accessing content from a NAS. AFAIK outbound and return traffic has always been allowed. What firewall on Linux makes you click every time for a network connection - I've certainly not seen one?
