-----------------------------------------------------------------

This is still valid with pyarrow 0.13

We don't validate neither at the python side:
https://github.com/apache/arrow/blob/master/python/pyarrow/table.pxi#L289
nor in the ChunkedArray constructors:
https://github.com/apache/arrow/blob/master/cpp/src/arrow/table.cc#L42-L63
