In light of diversifying ocean biomes, flora and fauna, I propose a new depth of water.
Shallows are ultimately something that can be foraged during a regular walk, you can properly see what is at your feet and as such we can forage and view them from our bipedal position.
Deep water is dangerous, requires swimming and stamina to cross, its depths can be completely unknown, and it is most suitable to traverse via watercraft.
I think it would make more sense for worlds to be generated with a new type of water biome, an intertidal type of zone, a middleground between deep water and shallow water.
Why does this make sense?
Shallow water should be more rare, more as a thing that is paired with sand and skargard and not occurring on its own very often.
Most rivers and practically ALL land should be 100% guaranteed to be surrounded with this intertidal water depth.
This will allow a few major improvements,
1 - the idea of massive ships and whales to not be able to traverse super shallow water because that is retarded
2 - the idea for all caves and cliffs that spawn at the edge of water to be safely traversed and entered without the risk of drowning
3 - the ability for animals to cross water more often (this depth of water would be something that makes up the majority of rivers)
The other reason I suggest this water is to dramatically expand water flora and fauna.
Many ideas have been proposed on how to make the ocean and water areas feel more alive
Ocean Biome Diversification
Ocean Flora Diversification

Brackish Water Flora & Fauna
This biome could have an entirely different group of forageables than shallow water and be more of a risk-reward situation.
My though is as follows - you must literally "go underwater" to forage this depth of water.
It would act exactly like a level 1 cave, you can do a quick "look" underwater like with the eyeball thing, the same way you would look in to a cave, and upon entering this depth of water you have an air timer that could be relative to your constitution or stamina and deplete until you surface again.
This could add for some interesting strategies with pve and pvp if entering "under water" would disengage you from an agro? Just a thought.
It could also add an unprecedented level of risk/reward to foraging and allow for a long term expansion of complementary mechanics. (think spear fishing, clam digging, etc.)
Imagine it as a difficult-but-entirely-possible to traverse biome (similar to thicket?). So many problems solved, so many windows of opportunity opened.
Thank you for reading this top idea.
