The package relies on dead libs like orbit and gconf. Also... I am not sure if many people would still use it this days (there are many browser extensions for example to watch SMS when they arrive and many other notifications). Personally I would treeclean it because of the usage of old libs, dead upstream and probably low amount of users at present time
Did the last porting efforts to newer APIs, long ago. Project didn't move since then, I say go and delete it from tree.
