better underwater ruins

Underwater ruins. In my experience they only are useful for sea lantern or the fact that they spawn drowned. Though they do sometimes spawn with chests the loot inside of them usually is not that useful especially for the risk. For example, early game an underwater ruin is harder to enter and leave with worse loot that a shipwreck that is much easier to loot giving amazing items. Underwater ruins should have some sort of larger benefit either a later game benefit like a drowned spawner or more prismarine and sea lanterns, a better loot chest for example would give benefits throughout the game with loot like nautilus shells or gold, diamonds, iron or emeralds. I was also thinking that maybe since the ruins are built like ruined models of villager houses that there could be a blacksmith ruins with a chest similar to the ones in a blacksmith. I am not sure what the best idea here is but I think that underwater ruins need to be improved. Leave your own ideas, suggestions and improvements in the comments!
