Don't worry woodpecker, this was more for Elizabeth BS, disputes can be resolved with disputed_by and claimed_by tags, but not with wrong boundaries or corrections just in your opinion. My suggestion in all disputed regions is to create 2 relations, one de facto and one de jure, with claimed_by and disputed_by and everything is then mapped correctly, both variants are present. There are many disputed territories around the world with a larger area than this one river island and all local communities are having a chat and found solution that works for them all. Just by finding some map does not mean you should go over and apply it.
