Crazy idea: Make warding the junglers job? Make sightstone into a jungler item?

I mean that role already is all over the map anyway, might as well drop off some wards along the way. So why not give him a altered sightstone that merges with his normal jungle items? Take it away from the support and that role is now 800 gp lighter in mandatory items and you have an extra slot.

I have no idea what the ramifications would be for the game, its just a crazy idea, feel free to comment.
