Yaron Gvili commented on ARROW-15571:
-------------------------------------
Since plenty of NaN values exist, I find returning an input NaN value more
user-friendly then returning a null, which just drops information, which can
always be done in a later step. However, if there is a convention that other
operations conform to on this issue, then it should probably be followed on.
