I found a nice little script that prints an ASCII network diagram of your routing table. I had to snap it 
The snap uses ip to get the information it needs, and I think network-observe sounds like a good one to grant for that. It’s not that user friendly to ask the user to connect these interfaces after install time so I ask if network-observe could be auto connected for the snap graphpath?
