The main problem with implementing a fix was that it's unclear what the
desired result even is. After some discussion with Max, I think we'll
try it with restricting snapshotting to everything that is directly
attached to a BlockBackend and monitor-owned nodes that don't have any
parents.
Yes that is what I would expect as well, and possibly also consistent
with a 'drive_add with if=none' being used but not the corresponding
-device. (thus no frontend).
