I think that's true, otherwise it second guesses the default behavior
of Btrfs when a volume's devices aren't all present.

But conversely right now there is no way to proceed with manual intervention.

That's being floated on the Btrfs list also. The caveat is this ends
up looking something like LVM's dmeventd or mdadm --monitor daemon.
