well, that's a little unfortune compared to a setup not using
systemd-networkd where you can *temporary* disable interfaces just with
"ifdown lan4" without changing a configuration
the point is *temporary*, changing the config means it would be disabled
at the next boot too, on a machine acting as router/switch temporary
disable interfaces makes a lot of sense to disconnect a client from the
network
