Review Comment:
   Looking at the list here, I think most of the features that C++ supports are also exposed in pyarrow, I think. 
   Although I don't know if writing a type like UUID (that doesn't exist in arrow) is possible with the direct Parquet C++ API? (that's not possible through the Arrow based writer, I suppose, and so also not in pyarrow)
   
   If we only keep the C++ column in the table, we should also add somewhere a note that this implementation is also exposed through Python, R, GLib, .. bindings. 
   (another reason to not include Python, because then why not also include R, etc)
