If the archive is exctracted on double-click into a new folder and the new folder is opened with nautilus some users might allways double-click the archive to get to the files again. In result, there are a lot of folders with the same content, but named "archivename1", "archivename2" etc. Because the user thinks that he has to double-click the archive file in order to get to the files.
I think the whole archive thing is a problem to new unexperienced users. Maybe, the first time file-roller is opened, there could open a window with some explanations about archives.
I think the fact, that there is a new folder, when the archive is double-clicked would only confuse the user.
