> once you have set up your rules for your most frequently used applications, it isn't really an issue

I can second this, also if you're overwhelmed you probably have a lot of garbage applications making too many outbound network requests to trackers and who knows what else which is actually nice to know about. Chrome-based browsers and Electron based apps seem to be particularly awful about this. My HP printer app tries to connect to Google Analytics, Microsoft RDP phones-home before connecting to a session. I really value that kind of insight and enjoy being able to control it.
