What they have done is taken the chaos of networking scattered across 1/2 dozen (or more) configuration files and commands and centralizes so the chaos is in one place. They've succeeded in simplifying some parts and I have faith they will make network configuration much simpler in the future.

You only think ifupdown-ng, nmcli/nmtui work well because you don't remember how hard it was to learn and developed scar tissue from using them. To my scar tissue, Debian/Ubuntu is well organized and tools like netplan clicked very fast and make network configuration much easier.
