> createDataFrame of local rows differs from PySpark 4.3.0: a NumPy array in an
> array field raises AssertionError (PySpark takes it when the elements need no
> converter), an int for a DateType field raises ValueError (PySpark takes it
> as days since the epoch), and a nested struct with duplicate field names
> sends IPC that the server cannot read (PySpark deduplicates the Arrow names).
