Despite the Dawn team wanting this to be a very primitive body dating back to the Dawn of the solar system, there's no particular reason why it could not have been larger at a very early date and to have lost a lot of mass though large impacts to become what we see today. I only suggest this to say that the grooves may be explained by events whose records are no longer visible to us. It's like Phobos - everybody wanted the grooves to be the result of Stickney despite the fact they have no geometric relationship to it at all. At least we can lay the old story of Mars ejecta to rest at last!
