The only junglers(to my knowledge) that rely on magic damage to kill creeps are Batrider and Dark Seer, so giving magic resist to jungle creeps would only nerf those two's jungling ability. Batrider would need a significant buff to make up for this, Dark Seer already needs a nerf so this would be an okay one.
wildwing tornado and satyr shockwave are both magic; adding magic resist immediately and dramatically affects the two most useful spells for chench to clear camps
