The 'edit' file in root directory => Quest decks editor

There's a feature well hidden in Forge - if you start with file named 'edit' in ur directory, the deck editor for quest mode obtains a new submenu... it's purpose it not very clear to me, because AI decks are now stored in forge\res\quest\decks\ and can be edited via standard deck editor, so I guess it is not needed there and should be removed.
Is there any reason why I should keep this hidden menu? Is anyone still using this?
