It's great that we now have a more standardize way to define this in udev!

In Netplan we faced this issue a lot over the years, when users had
configurations using multiple backends at the same time, e.g. some
interfaces set to "renderer: networkd" while others were set to
"renderer: NetworkManager" in their Netplan configuration.

It was solved by controlling the ENV{NM_UNMANAGED}="0" variable via udev
rules and configuring the [device-*].managed={true,false} NetworkManager
settings accordingly.
