Don't know whether I'm wrong, but what should that be good for? If you want to create a hidden script, you have to give it a password. Also when you want to edit it, and in my opinion it's roughly the sense of a hidden script that you only can access it if you know the password. Let's assume it would be possible to access it from API: you would supply the password in plain text in the module - so the hidden script would not be hidden any more. Even if you would NOT supply the password you would have to type it in when executing the macro - but that would be against the sense of an automated process ....
Perhaps I'm totally wrong, but that's my point of view,
