The same consideration has to apply for when the mesh device disconnects
the eth device, because the user requested a mesh connection. Right now,
NM immediately reactivates eth0 (usually reconnecting to the same
network as before) and "wins."

What is the "device idle" concept? What do you think of an approach
along these lines? This way the mesh device can attach to the
autoconnect-allowed signal on the main device, and influence when it can
and cannot be used for automatic connections.
