I agree with you. There are many disputed borders and areas around the world. OSM as neutral platform should in clear manner and objectively preset how border lines are seen from any party included that claims the land or the sea. If we follow practice as it is now: de-facto control over the area, we stumble at the same problem, some areas are in conflict and there is no de-facto control, on other hand if OSM present one border as the only possible one that means it is getting biased and discriminatory.

So if goal of OSM is to present world as it is as accurate as possible, it shouldn’t close its eyes from real problems that are border disputes.
