ClickHouse has support for trailing commas for several years. I recommend looking at ClickHouse (https://github.com/ClickHouse/ClickHouse/ https://github.com/ClickHouse/ClickHouse/) as an example of a modern SQL database that emphasizes developer experience, performance, and quality-of-life improvements. I'm the author of ClickHouse, and I'm happy to see that its innovation has been inspired and adopted in other database management systems.
