 reordered should call `FileScanConfig::preserves_file_order()` instead, which
 also accounts for the output ordering.

+### `ParquetFileReaderFactory` adds `Any` as a supertrait
+
+To enable downcasting of `dyn ParquetFileReaderFactory` to concrete factory
+types (via `is::<T>()` / `downcast_ref::<T>()`), the
+`ParquetFileReaderFactory` trait now has `Any` as a supertrait:
+
+```diff
+- pub trait ParquetFileReaderFactory: Debug + Send + Sync + 'static
++ pub trait ParquetFileReaderFactory: Any + Debug + Send + Sync
+```
+
+The trait already required `'static`, which `Any` implies, so existing
+implementations need no changes. `ParquetSource::parquet_file_reader_factory`
+returns the trait object to downcast.
