The issue is the same as that of the OTU: a consistent publishable setting.
Since Sunbane generated its data, there has been interest in at least fixing inconsistencies in that data set against Atlas of the Imperium - which is what Far Trader and I did back a few years ago. I believe at least some of that data has propagated into Travellermap.com.
Similarly, Don McKinney has worked over the Spinward Marches; those changes are planned to go into Travellermap, if they're not there already.
