Hopefully it will be supported soon. Just not quite yet. It still requires some work, so that's why if you tried the recently released 1.9.0, it wouldn't detect it - the official releases only support completed games. But you can always try a daily build in the meantime. Though right at the moment there's in-progress work being done on the title screens and cutscenes, so you won't be able to get into the game proper unless you fiddle in the source code.
In terms of priorities, I'm currently spending more of my time working on Starship Titanic than Xeen. So I'm not sure when I'll be done. But I am committed to seeing it finished, and am spending at least some of my time on Xeen.
