This does not add a deprecation warning primarily because it's a bit difficult to do (we would need to check the data types whether it's a date -- or in the case of a table, if any field is a date--, and then warn if so). `True` is the correct option though in order to accurately roundtrip data to and from pandas. Some users might have some workarounds floating around, but this is sufficiently advanced stuff already. With this patch, date data round trips with no special options ``` In [2]: import pyarrow as pa In [3]: import datetime In [4]: arr = pa.array([datetime.date(2000, 1, 1), None]) In [5]: arr Out[5]: <pyarrow.lib.Date32Array object at 0x0000022CCDB1BBD8> [ 10957, null ] In [6]: arr.to_pandas() Out[6]: array([datetime.date(2000, 1, 1), None], dtype=object) In [7]: pa.array(arr.to_pandas()) Out[7]: <pyarrow.lib.Date32Array object at 0x0000022CCDC7FE58> [ 10957, null ] ``` If others strongly feel it's worth going to the effort of raising a deprecation warning, please chime in.
