I agree that adjustments to the coastline are a delicate matter and require a good reason. However, I have personally seen the situation around the marina Breskens. The previous coastline around the sanitary building was inaccurate. I believe that my adjustments make the map more accurate, even if the changes may take some time to appear in renderers.
As for the pier, I will certainly add it to the map as an area.
Thank you and best regards.
