Yeah, DuckDB has some very cool features, but I with the community were less abrasive. I remember someone asking for ORC columnar format support, and DuckDB replied "that is not as popular as Parquet so we're not doing it, issue closed". Same story with Delta vs Iceberg.

Meanwhile Clickhouse supports both and if you ask for things they might say "tha tis low priority but we'll take a look". Clickhouse-local can work as CLI (though not in-process) DuckDB too.
