Deeper Oceans biomes!

With the recently changed and expanded world generation I think it would be really interesting to at a future point make the oceans deeper, with deep sea creatures added as well. This update could also perhaps include a deep sea monument or other structures of any kind, creating incentive to explore the depths of the sea. I believe this would also add a general incentive to explore the oceans. As personally myself and many people I know included don’t tend to explore the oceans much further past the ocean monument.
