> For projects that depend on the DataFusion logical plan, there is a breaking change currently compared to 2.0.0 where it is not possible to introspect the TableScan node for CSV and Parquet files to get the file path and other meta-data (such as delimiter for CSV).
> I propose adding public methods to the specific providers so that other crates can downcast to specific implementations in order to access this data.
> My specific use case is the ability to serialize a DataFusion logical plan.
