Unless the file is very small, the column would most likely not be in the same byte range. Duckdb also can't filter on multiple columns without fetching both. Being able to fully preselect data at the source is much more powerful than the parquet tricks duckdub uses. Don't get me wrong, the duckdb impl is good and generic and will support any parquet store, but it is not as powerful as S3 select.
