That flag, is a MAJOR privacy improvement.

If "All" really includes "all" networks.

Before, "some" undefined traffic to Apple systems might be routed outside the 
VPN.

I guess this is so that Apple Private Relay is private, and other VPNs, eg 
wireguard, can't say "but you still route traffic elsewhere" like before, which 
would be an unfair advantage.


Thanks Apple Employee X who arranged getting this in! Very very much 
appreciated!

Greets,
 Jeroen
