Increased difficulty for Piglin Brutes

The newly revealed Piglin Brutes do a good job of filling a difficulty gap of bastion remnants in the new Nether Update, but there is still something missing from them. While they do have high hit points and damage, they are still barely a threat for players in the nether, and won’t pose that great of a threat when trying to get bastion chests, arguably the one of the best treasures you can find in the game. In the theme of the nether, netherite armour introduced knock back resistance, so I think crossing the bridge to netherite should face players against a knockback-resistant enemy, never before seen in regular mobs. Piglin Brutes are perfectly suited for this addition, as it is easy enough to continuously hit them away from oneself. It would change the way players would have to think about raiding bastions, from mindless sword swinging combat, to having a battle plan ready to defeat Piglin brutes. This should in turn have the brutes classified as mini-bosses (as they should be, they exist to guard treasure that has a chance to contain netherite!)
