> Indeed - hopefully this indicates a trend toward better compatibility and standardization between Gnome and KDE. (If just those two could agree on things, and they were open enough that Xfce could be compatible, we'd finally have a "standard" Linux desktop for application developers to target.)
That trend has existed for years. GNOME, KDE, XFCE, and other environments already agree on quite a bit. Many standards exist to make sure applications from all of those environments interoperate, and new standards (such as this one) pop up frequently to unify common functionality.
