Changing the renderer to NetworkManager still leads to a working system with live connections, even with the NetworkManager files now having a .nmconnection extension:
ubuntu@just-boa:~$ dpkg -l netplan.io | grep ii
ii netplan.io 0.96-0ubuntu0.18.04.2 amd64 YAML network configuration abstraction for various backends
ubuntu@just-boa:~$ networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
