Enhance the Deep Ocean Biome

The Deep Ocean Biome was added in 1.13 - Aquatic Update. At that time, the concept of negative height (y-) did not exist; so the deep ocean was not that deep. Once 1.18 comes out, it would be inconceivable that not only the caves are part of the negative layers, but also of the titled biome: aesthetically it would be appreciated as a kind of cliff but sunken, the shiny squid would mostly appear and, why not, the monster from the depths (mob that participated in the 1.13 vote, in which the ghost won); It would be great if Mojang returns to this mob and has the same glowing effect as glowing squid or enderman eyes, but in red. Who knows ... maybe another mob would appear with the same glittering effect. Have you seen the movie "Finding Nemo"? Well, in a specific part the ocean appears but dark with glistening fish.
