If the proposal is accepted, you'll get this feature as:

    $qb->add_constraint("metadata:ancestor", "=", $guid);

You can even limit the query to all the ancestors of a given
descendant node with:

    $qb->add_constraint("metadata:descendant", "=", $guid);

The more limited "metadata:parent" and "metadata:child" constraints
limit those queries to just one level down or up from a given node.
