What feature or improvement would you like to see?

As of Polars 1.33.1 __arrow_c_schema__ was introduced on Polars.Schema (pola-rs/polars#24365)

As of Polars 1.32.1 (which was yanked, so really 1.32.2), Polars.Schema can be initialised from an object with __arrow_c_schema__ (pola-rs/polars#23879)

I believe this means adbc_get_table_schema can be implemented for the Polars backend (correct me if mistaken).
