Wearing stronger armor increases enemy aggro

Wearing stronger armor should make enemies be able to see you from further away, and ranged mobs should attack from further. This effect could be jointly proportional to the defense points of armor and the local difficulty in chunks. Doing so could provide some more use for armor besides just looking swanky. It also makes sense for enemies; when they see you in fancy netherite armor, they would know that you're stacked and try to eliminate you more quickly.
