Armed Villager Defenders and More Raid Enemies

Right now, villagers mainly rely on Iron Golems to protect them. Iron Golems are useful, but a single golem can die quite quickly during a large raid, especially when there are witches and different types of hostile illagers. My idea is to add defender villagers. They could be villagers who are trained to protect their village and can use swords, bows, shields, and armor. Different defender villagers could have different equipment. Some could fight with swords and shields, while others could stay behind and use bows. They wouldn't replace Iron Golems. Instead, they could work together with them, making villages feel like they actually have their own small defense force. To keep the game balanced, raids could also receive new illager enemies with different abilities or roles. This would make raids more challenging without making defender villagers overpowered. I think this would make villages feel more alive and protected, while also making raids much more interesting and strategic. There are already mods that add similar features, showing that many players enjoy this idea. However, having an official version made by Mojang would make it accessible to everyone, including players who don't use mods.
