Goal: Determine whether the -hi flag on the xform -q -ws -bb command causes the returned bounding box to encompass the geometry of all descendant shapes or only the transforms themselves.

Uncertainty: The Maya documentation for versions 2022 and 2024 differs on this behavior, with some releases stating that the flag includes the full hierarchy and others implying it only affects the selection of transforms, leaving the exact scope ambiguous.

Does the -hi flag include child shape extents in the bounding box calculation? Does the behavior remain consistent across Maya 2022 through 2024, or does it change between releases?
