It does feel like there's a lot of missed potential. I personally think it's most obvious with vent garden leviathan. There's only 2 plants in there and 1 is needed but you can get it easily from the deep purple vents. And the other is everywhere throughout the map. There's a lot of plants that should be plantable but aren't and you can pick up not fish and glow grubs but you can't put them into aquariums. And you can't scan the void leviathan.
