I think it would be quite immersive to see the wreckage of ships near the maps border edges to give the impression of those who tried to enter (or leave) the sea of thieves and got claimed by the shroud.
Perhaps it's something that could be added for next gen.
Could be like a graveyard of ships in some areas, other areas not so many shipwrecks like maybe one or two.
A few wrecks could even have the colours of the Grand Maritime Union to hint at the Lore beyond the shroud.
It would be a nice touch for immersion I think.
