I disagree, I think it is standard practice. Nagorno-Karabakh is a region geographically and politically within the autonomous, independent and internationally recognized country of Azerbaijan. The region's population is mostly Armenian. On December 10, 1991, the Armenians from this region held a referendum and declared the region independent. To this day, the self proclaimed Nagorno-Karabakh Republic remains not recognized by any single country in the world, including Armenia. Yet both articles are still listed within the scope of both Wikipedia:WikiProject Armenia and Wikipedia:WikiProject Azerbaijan. The political and historical notability to an encyclopedia will not end from the Azerbaijani perspective if the world ever recognized N-K as independent and, likewise, Armenian interest is also notable. Inclusion of the article into WPArmenia does not imply the region should belong to Armenia or the Armenian people. It's simply a topic that Azerbaijani and Armenian editors have knowledge of and can contribute to it. The article on Serbs of Croatia is no different. I agree with DIREKTOR that this is a touchy subject (it may be an understatement, actually) but the article's inclusion into WPSerbia is not politically motivated, it's encyclopedic.
