Not Saint here, but November 2023 is still pretty recent compared to the release date of some of the other ones on the list (eg Chosen), and also, I suspect that like what Saint said about RoD, to upgrade QL would mean integrating the new insights into not just one dense script, but four of them.
Also I suspect they probably want a chance to see feedback from BL: ITW before considering further improvements to other cognitive enhancement titles.
