Somehow I dont see this applicable for 90% of all current spatial needs, where PostGIS does just right, and same IMHO goes for DuckDB. There perhaps exists 10% of business where data is so immense you want to hit it with Rust & whatnot, but all others do just fine im Postgre.
My bet is most of actually useful spatial ST_ functions are not implemented in this one, as they are not in the DuckDB offering.
