no surprise I missed it, 3.4 was only released in 25.11.2024 г. which is like yesterday in ESRI terms, given price and speed of adoption of new versions (note: many .gov still use the 10.x/11.x branch).

which does not change my original statement that nobody cared about DuckDB for very long, while the whole server-side processing idea is largely based on PostGIS.
