hi..
            
            i noticed a new branch when i pulled kde-workspace today (finally!): 
            activities_optional
            
            the lone commit in it was pushed on april 1, so maybe it's an april fools 
            joke, but if it isn't, it looks like someone is trying to do something that 
            makes no sense (and has no chance of being merged into master). so if this is 
            a "for reals" branch, perhaps the motivation behind it can be shared?
