*I think* it is due to incomplete overloads for all of:
-
[`ChunkedArray.type`](https://github.com/rok/arrow/blob/5ab15e7618120a33ca6af440ca68093f102aef54/python/pyarrow-stubs/pyarrow/table.pyi#L136-L137)
-
[`chunked_array`](https://github.com/rok/arrow/blob/5ab15e7618120a33ca6af440ca68093f102aef54/python/pyarrow-stubs/pyarrow/table.pyi#L264-L281)
