We have to maintain homogeneity of the whole Lithuania, not some specific small parts of it. Therefore we attach classification to official/government classification. This has been discussed and agreed long time ago by Lithuanian mapping community - otherwise classification is subjective: people constantly change it according to their own understanding, different uses tend to "want" different classifications which lead to pointless disputes etc. Current classification also adheres to the rules of cartography where temporary permissions have no influence. If it is not possible to pass - you add "access=no" (or similar). If you want THAT to be very visible on a map, you would then... well have to create your own symbolisation of that information.
