The new spec says that if the notification system doesn't support it, it
"can be addressed by removal and addition instead".  I agree that's a
little vague; the goal is to have only one notification where the newer one

The previous language was:
    5. If the underlying notification platform supports replacement,
replace old with new on the device.
    6. If the underlying notification platform does not support
replacement, remove old from the device and show new on the device.

Anne, can we restore that language consistent with the new task structure?
