copy_data is an option of the action, not a property of the
subscription. The difference between those two things is admittedly not
clearly (at all?) documented.
However, I'm not sure whether creating a subscription that always
defaults to copy_data=false for tables added in the future is useful
functionality, so I think the current behavior is okay.
