   The suggestion is never to push offsets down within ArrayData, and so you should never have this ambiguity? 
   
   When constructing an instance of StructArray you "hydrate" the offsets to boxed fields to avoid having to recompute slices on access, but this does not modify the underlying ArrayData?
