Just to add some weight here - instanced geometry would give a huge benefit to some FlightGear features (random buildings and trees, and possibly clouds), but given the limited size of uniform arrays, we would need the extension above to position instances. Is there a way to use it with the existing code, or is a (hopefully small) enhancement required?
