We're looking into this and it should be fixed in the near future. We definitely agree that it should support multiple authors.

As of the moment the authors tag doesn't show in the mod list at all. Marking TODO and Low Priority because adding it wouldn't do anything noticeable in-game. I need to get hooked into the Gui mods list and inject our sudo mod containers.
