Hi all,

I have a question about writing nested datatypes to Parquet files. I noticed 
that the use_compliant_nested_types option is set to false by default. I was 
wondering if there was a particular reason this is set to false by default. I 
noticed a comment in 
parquet/properties.h<https://github.com/apache/arrow/blob/be665ef948cb2c6706c60053c5db918e948713e8/cpp/src/parquet/properties.h#L650>
 suggesting the default should be flipped to true at some point. Is there a 
reason why you wouldn't want to set this option to true?

Thanks,
Sarah
