text: I too think they are historic and potentially confusing, but tell that to German mappers who come from time to time to edit Poland and fill the map with such names.
  
  The case of German exonyms in Poland was never standardized by Polish and German OSM communities, really.
  
  There's apparently committee in Germany that standardizes exonyms (equivalent of Polish KSNG), but I was not able to track down any gazetteers they produced, if there are any (KSNG publishes PDFs, for example).
  
  Creating a thread at the German forum to discuss the issue would make sense to me.
