Relation 2017003 is admin-level 8 boundary that is VERY rough (and even cuts out part of the island. Relation 3789009 is very exact on the island. It might be reasonable to change relation 2017003 to match 3789009 and delete 3789009 then as dupe?
Or is the existing boundary for some reason like this?

Changed admin boundary on July 1st. Administrative island boundaries in DE might cover parts of water and also cut out parts of land. That's a fact. Never make land area and admin area match in DE! In this case the official admin boundary even is completely shifted with no overlap with the actual island (when Bing aerials are not completly wrong).
