I’m guessing this judge considers the telephone to be an example of negligent design as well. After all, the phone company doesn’t record every phone call I make and disconnect me if I mention an illegal drug.

Doesn’t systemd have the ability to do this as well with unix sockets?

I don’t recommend using the shell on routers for day-to-day management. Instead, consider using a network configuration management system like rconfig. I’ve used RANCID in the past, but I suspect something more modern like rconfig will be useful to you.
