Same with not allowing fine-grain control of what apps are allowed to use your WiFi/connect to the internet. I don't give a shit that an app feels entitled to it, its my internet bill and its already implemented perfectly for your cellular data stuff. There's no reason or excuse its not a privacy setting that you can tightly-control and revoke.
This would be excellent, because most apps and even iOS shits the bed when it is on a WiFi network that can't reach out to the Internet. They expect it to be there and open all the time, and show me all sorts of Fisher-Price "Uhoh! Your WiFi isn't working!" errors when in fact it is working fine, and I'm completely aware it can't connect to the Internet because I'm the one who configured the firewall.
