Very nice and simple too!
Missed this in my search (damn, finding projects in github is _hard_).

Of course, I was hoping to get more detailed events out of networkd. I
wrote something very similar for connman, where I can get events for AP
reconfiguration and DHCP updates (including resolver changes) in a
single spot.

For a wlan link, I really want to know which ESSID wpa_supplicant
attached me to.
