Since, as you say below:

couldn't it simply relay the GdkEvent from which we can infer the type
(button or key or whatever) and drop the <button,timestamp> tuple?  The
GdkEvent would give us the coordinates for the exact renderer using the
gtk_tree_view_get_path_at_pos().

Otherwise, you would have to pass the <x,y> coordinates too, and that
would make it look a bit uglier.

Other than that, I think it could be useful to have this signal.
