> Currently, the {{list_parent_indices}} output type is the input list offset type. But that doesn't really make sense: the parent indices are simply indices in the list array, they are not bounded by the offset size (even a list array with 32-bit offsets can have a length larger than 2**32, for example if it's mostly nulls).
