Comment 7 for bug 12682

This is actually explicitly against the Gnome HIG. From http://library.gnome.org/devel/hig-book/stable/principles-match.html.en :

"When using metaphors, however, it is important to neither take the metaphor too literally, nor to extend the metaphor beyond its reasonable use. For example, the capacity of a file folder should not be limited to the capacity of a physical file folder, which presumably could contain only a few documents before becoming unwieldy. On the other hand, a waste basket should not be used for anything other than holding discarded files. It should not be used, for example, to eject a removable disk such as a floppy or CD."

Also nautilus now has eject buttons on volumes starting in Intrepid so I think this is arguably both deprecated and undesirable.
