Yes. v2 drops the root exclusion, so the attribute is attached to every
adapter of the mux tree, the root included. Matt asked for the same
thing, to be able to remove a root netdev at runtime.

I have no USB-attached adapter here, so the hotplug ordering is
untested. The attribute is attached from the bus notifier as an adapter
appears, which should cover one arriving after the controller is bound.
