I agree that it is a good idea to be explicit about this behavior. As mentioned by you, it would be better to backpatch this. Also, I thought about moving this to some other section like [1] but I think we need to explain a bit about apply worker before providing this specific information. So, the current place seems to be the best bet considering the way current logical replication is documented.
