Joris Van den Bossche commented on ARROW-7806:
----------------------------------------------
LargeString and LargeBinary conversions were added in ARROW-6115, but not yet
for the "list of" case, only the actual types.
> [Python] {Array,Table,RecordBatch}.to_pandas() do not support Large variants
> of ListArray, BinaryArray and StringArray
