Where the default is unset, I guess?
But then, what about the resuming of the parents before the device is resumed?
Should the parents be resumed regardless of the flag state? And if so, what's
the condition for breaking the recurrence? Surely it's not sufficient to check
if the parent is active, because its parent need not be active if it has this
special flag set.
Best,
Rafael
