Along the same vein as the decision to include Shotwell by default,I would like to propose the removal of Tracker from the default GNOME installation pattern in 12.1
Unlike previous versions, tracker is no longer well integrated into GNOME - it is not used by the gnome-shell search which largely replaces the SLAB search from our G2.
Desktop indexers also do not appear to be as popular as they once were (Google Desktop is being pulled, etc)
Desktop indexers can be horrific drains on performance, I think if we remove tracker from our default 12.1 install any newcomers will be pleasantly surprised at the performance improvements
Of course, I'd still like it in the repositories - so people can install if they want and upgraders can keep their tracker functionality
