I dont see why Gnome as a whole depends on Empathy.

On a separate note, the task selection in the installer governs which 
packages are installed by default.

If I wanted to make a custom derived distro presumably the first point 
of call (after creating my own repository and copying all the stable 
packages to it) would be modifying the task selector to alter what is 
installed by default?

But Im a bit perplexed by why Gnome as a whole is dependent on what I 
see as simply user apps on top of Gnome which Gnome should be able to 
function perfectly well without.

To me the package dependencies here are screwed? Removing an IM client 
or a web browser shouldnt cause the whole desktop environment to be 
removed too.
