Entity Aging

All entities (except player) die over time this will provide a balance to the game and a more imersive experience for example a villager with mending will after a while despawn this allow the player to have a more challenging experience knowing that the time is limited perhaps this can be even turned of in world settings or cheats I understand that it would literally be adding another code into every single entity to which I also understand if this idea is overlooked I just feel it would add so much and bring players closer
