Weston Pace commented on ARROW-13269:
-------------------------------------
One question to consider also is whether we need to fix the behavior when
use_legacy=True or require users to migrate away from legacy if they want this
fix. Right now both fail, but it would be easier to fix use_legacy=False than
the older code I think.
