With the addition of "Rough Water Tiles" that do damage to your ships depending on conditions, I think it's now with in bounds to add Wild Animal Tiles, especially in Civs that have a large animal populations(India, Africa, Australia etc.).
It would apply to a few Rainforest, Wild Plain, & even Jungle Tiles(If that exists, I'm new).
How it works is, as you approach, the Wild Animal Tile appears, & you can use the prey/docile as you typically did in Civ 6, but Predatorial Animals become an Obstacle, you can go around or fight like you do Barbarians. One difference is this tile can be used as a form of defense for your civilization, as an Obstacle for opposition forces, approaching your Civs.
Maybe you can eventually make a Unit called Animal Trainer that makes these Animals either Entertainment for a Circus or Defense/Attack Units
