It would be good if MAAS adds support for the groovy version. All the other bits and pieces seem to be coming along.
I am thinking on creating an specific connected power supply for RPIs, ammong others.
Based on the ESP32, for which there is Ethernet support and many openhardware projects + some reles.
I also want the same setup to power other devices such as the odroid-h2, that I am using for creating maas clusters.
