> It seems like [WriteIndices|https://github.com/apache/arrow/blob/0c8b861f93884f2868eb631d8fceee3a8b8905ec/cpp/src/arrow/python/arrow_to_pandas.cc#L955-L981] could reuse some of the logic in [ConvertValuesZeroCopy|https://github.com/apache/arrow/blob/0c8b861f93884f2868eb631d8fceee3a8b8905ec/cpp/src/arrow/python/arrow_to_pandas.cc#L1348-L1385] to avoid copying the integer indices array?
