[xmonad] What happened to ScreenWorkspaces?

Does anybody know what happened to the ScreenWorkspaces module, mentioned briefly here? http://article.gmane.org/gmane.comp.lang.haskell.xmonad/7223 It sounds useful, as it seems like it would extend Xmonad.Layout.IndependentScreens to also allow for a more polished experience (notably, perhaps it would fix CycleWS behavior as discussed at http://www.haskell.org/pipermail/xmonad/2009-December/009466.html). Also, it would allow for a more Gnome-like multi-head experience (as mentioned at http://article.gmane.org/gmane.comp.lang.haskell.xmonad/7774). Mike
