Leather Armor makes you quieter and sneakier

Currently, mobs detect you at 16 blocks away when you’re walking, around 12 when you’re sneaking, and IIRC around 4 when you’re using an invisibility potion. On top of this, in multiplayer, players cannot see your name tag through walls or more than 32 blocks away when you’re sneaking. I propose that the stealth buffs that come through sneaking should also be applied to a full set of leather armor, and as for mob detection, it would have an additive effect with crouching and invisibility potions. This is to give leather a definitive niche - it would especially come in handy in competitive multiplayer games where it might be preferable to wear leather armor and sneak into an enemy base rather than wear diamond or netherite and fight your way in. Furthermore, it would be nice if leather muffled sounds produced from walking so as to lower the warden’s detection radius.
