Sarc's Suggestions

Several additions change how ordinary mechanics behave: poisonous potatoes can be planted and used to craft herbicides that clear grass, mycelium and leaf blocks, and heavy weighted pressure plates send out a redstone signal scaled to the maximum health of the entity standing on them. Mobs can be made to ride llamas, though other llamas and wandering traders are excluded from that.

Livestock animals such as cows, chickens, sheep and pigs become paralyzed with fear when a polar bear is nearby. Lost gear that despawns can sometimes reappear in the trade offers of a wandering trader. Feeding a bat a spider eye sets the player's current respawn point to a new location.

The mod is licensed under the MIT License and is open source, so the source code and issue tracker are public. It needs Fabric and is published for 1.16.4 and 1.16.5, with a single release file dated 2021-05-25 for 1.16.5. A server running it needs every connecting player to have it too.
