   @mapleFU To my understanding, Parquet writers still have to encode `ConvertedType` for each field according to the Parquet spec. So when you create a `PrimitiveNode`, its `ConvertedType` is automatically inferred and set from its `LogicalType` (see the constructor of `PrimitiveNode`). The stream writer can therefore always rely on it being present, except in the special circumstances which this PR solves. We can update the code of `StreamWriter` to check against logical types instead, though I see no special benefit for it currently.
