> Could we get a logged warning when a user tries to `pyarrow.parquet.write_table()` with `version=1.0` and a schema that contains an incompatible `uint32()` type? I don't think the behavior to upcast to an `int64()` is immediately obvious (although the docs are clear on it) and I think it would help prevent some confusion for other users.
