That does look nicer if you have a Parquet file and want to analyze it. But DuckDB is also a database - if you want a persistent, reliable and mutable data store I don't think Polars would be suitable would it? (Genuine question - you sound like an expert and I'm not.)
The other thing DuckDB does quite well, and which is out of scope for polars, is its keeping of an absolute zoo of external data sources you can query with SQL from the same database client. It's an excellent data warehousing tool.
