I was thinking selection vector/bitmap (possibly with different encodings),
but really nothing for now. Ordinarily, I'd lean towards YAGNI but there
isn't a good way to add this in easily in a forward compatible way unless
we add a placeholder enum/table for 1.0 (the default option would be no

Great John, I'd be interesting to hear about progress.
Also, IMO I think we should be only focusing on encoding that have the
potential to be exploited for computational benefits (not just
compressibility). I think this is what distinguishes Arrow from other
formats like Parquet. I think this ech

Thanks Joris for clearing that up! It's correct that pyspark will allow the
user to do operations on the resulting DataFrame, so it doesn't sound like
I should set `split_blocks=True` in the conversion. You're right that the
unnecessary assignments can be easily avoided if not timestamps, so that

What about returning null for a null list? It looks like now the function
returns a primitive boolean, so I guess that would be a substantial change,
but null seems more correct to me.
