Should more mobs be able to hear the player?

Sure, the Warden has super hearing and is blind, but why can’t other mobs hear the player too? If the player places a block for example, Zombies might walk towards the sound, while Skeletons walk away, incase the player is trying to build cover to help fight said Skeleton. New mobs like Ghosts for example could travel through walls, not seeing the player, but hearing them… spooky.
