Ryan Rossiter ea483ac1c4 Untie subobject versions
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.
