I think how Cordova works right now was the best way. Have access blocked by default, but have a <access origin="*"/> in the default template. It makes the setting visible, while still working out-of-the-box.
If we turned on requests when no whitelist plugin is installed, then existing apps that have <access> tags will have their whitelist removed with 4.0.0 and not know it. If someone updates and their app can't hit the network anymore, then I think Stack Overflow will tell them why pretty quickly. We should also be very clear in the release notes and upgrade guide.
