abandoned Shipwrecks in Mangrove Swamp and Swamp

I have an idea to adding abandoned Shipwrecks into the Mangrove Swamp and the Regular Swamp, because there are at the Time no Structures generating in Mangrove Swamps and in Swamps the only structure that generates are Witchhuts.

So to Improve the Biomes, you could add Shipwrecks stranded in the shallow waters of the swamps or wedged between the roots of mangrove trees
