Sometimes it could be useful to add objects to an extra layer for example to mark the region for conformal coating or add some comments/documentation. As far as I can tell from a fast look into a *.pcb file lines/pins/ElementLine/... any drawing object could be put on any layer which give very good flexibility for the future.
