Hi, I'm working through a certain use case where I'm unnesting ListArrays, but I noticed something peculiar - null ListValues are not retained in the unnested array.
E.g. In [0]: arr = pa.array([[0, 1], [0], None, None]) In [1]: arr.flatten() Out [1]: [0, 1, 0] While I would have expected [0, 1, 0, null, null]. I should note that this works if the None is encapsulated in a list. So I'm guessing this is expected logic and if so, what's the reasoning for that? Thanks, Suhail
