I don't want Evolution, Tracker and other packages in my computer (Ubuntu 14.04, GNOME 3.9, Shell 3.10.4), but GNOME depends on these packages . I've read some tricks for disabling some of them without really removing their packages. Despite this methods, I'd like to know the reason for doing GNOME this way.
I don't want to be FUD'ish (I've been using Linux for 10 years), but in Windows there is "Turn Windows features on or off". Given the architectural superiority of Linux in this sense, shouldn't it be easier to disable these packages?
