Some of the characteristics of the Confucian government are interesting- religious tolerance, restrictions on revocation and imprisonment, compartmentalized tyranny maluses, etc. Were these traits things that were already available to modders, or are they new additions? It seems like even if PDS has decided to leave China off the map, they're giving modders some good new assets to work with.
Also, it seems that Monastic Feudal boils down to iqta, but without duchy revocation or Turkish succession.
