Regarding you question, if you delete the BTOwner, the prefab will of course not show the blackboard 🙂
But any BBVariables will be rehooked when that prefab BT is used with another BTOwner that has a blackboard which satisfies the defined variables in the prefab BT.
Let me know if you have any more questions regarding that, be sure to send me an email for the new version 🙂
