stream data arrives for a relation it has not seen before?
If no table has been created by the user and we start trying to apply a data stream apply will break.
Since manual action is needed to create the destination I don't see a problem with requiring manual enabling too, personally.
Let the fully transparent way wait until we can do DDL replication in v11+
