I believe my original post was related to Hal and his buddies, Pango, and Dbus, otherwise known as Gtk2. It is that which has boarded the bloatmobile. So, Xfce and LXDE would also be considered as quite large.
While I think it is an admirable effort to offer such as extensions, don't expect them to be included in the base.
It is also MHO that the Linux Desktop should stop trying to emulate Windows, registry, key strokes, GUI, and the like. This is *nix and should be have its own identity.
