Since obj_relationships was removed in Iea8b6348e3b01aaa335ec5408f07826f1e758d20 because manifest backports are now used, most parent object versions will no longer change when a child object is changed. Because of this, some objects that have a child version tied to a parent version no longer need to be tied. The versions can progress individually on their own. The child is all grown up now, he's moving out of his parents' basement, buying a car, and going on to make his parents proud. Change-Id: Ie0c7bd419e3490d01f73c7a39cd2666eafcf9539
