    Silently allow child properties on grandchildren
    
    This commit simply removes some child->parent == container checks,
    to add some flexibility for containers with 'inner structure'.
    If these checks are considered useful, we can bring them back
    with a is_child vfunc that allows container implementations to
    decided who they consider legitimate child.
