Hey TheNewTeddy, welcome to the forum!
I still have the map here. Since then, me and Fornadan worked on the zoomed maps, which while not as all-encompassing, were a bit less cluttered and more informative. Regardless, since working on the zoomed maps, I noticed that I missed naming a few settlements here and there, and that still needs correcting.
Eventually I got busy with other things in my life and by and large stopped working on it. Fornadan has done quite a bit with the zoomed maps, including putting the commandery and province borders alongside names of settlements which only became reknowed in the Three Kingdoms era, rather than the Late Han.
If you're asking about the commercialization/publication of it, we just never got around to it.
It's obvious that the Atlas is quite a nice piece of work. I never went through the hoops needed to test print it, see what problems derive from being in physical form, find a company to produce the maps at a competitive cost, and then see the costs of bulk purchasing vs retail selling.
As for plain publicizing it, me and Fornadan never got to discussing that either. I know that Fornadan had a website where he planned to release the zoomed in maps, but then I dropped the ball, so I don't know how that progressed.
Ultimately, both of us did and do this as a side-hobby, so it was natural that some things just got stuck in limbo. I'm still of the opinion in trying to comercialize the main Atlas (after completing what is missing) and publicizing the zoomed maps, but all this requires that (at least for the maps where we both had a contribution, and every single map I worked on was based on his previous QGIS work) we both figuratively sit down and decide on what to do. For the maps that Fornadan did that had little contribution of mine besides the original translations, I of course defer entirely to him the decision on what to do with the maps.
From my part, right now I don't have the availability of going through the mentioned hoops to see if the main Atlas is minimally print-worthy, but I expect that in the coming months, I may be able to sort that out.
