This thinking is really obsolete and couching everything as grandma or graybeards is really ageist, anyway. Last I looked, you have to do this on Mac more often than I'd like. On Windows, it's open up CMD as administrator and paste this command or download and install this little app and run it (that does God knows what as administrator).
Maybe I've become numb to them, but I just don't see these painful interactions that get referenced, and don't see why their bogeyman would be worth giving up your freedom to use your machine.
Systemd, netplan, and many other things.
I am not sure what UNIX clones have to do with this
The latest version of Ubuntu you can not even set the IP with standard etc config, you have to use netplan YAML configuration
systemd has replaced all kinds of things with non "grey beard" configurations,
the list is pretty extensive
OS X configuration files (plists) can be XML based or binary, many are binary and managed via plist CLI or app.
