What sense does it make to have to use two or three different UIs to configure your network. Some stuff can get done under Settings > Networking, others under nm-connection-editor…

And to be fair NetworkManager’s networking implementation is a convoluted unreliable mess that doesn’t support half of systemd-networkd options and is incapable of handling changes to interfaces and links gracefully.

Even the classic Window network interfaces properties window is more consistent than what GNOME and NetworkManager offer.
