Old and Nostalgic

Some players miss the extremely old and Nostalgic textures of Minecraft from the first years, or others simply miss something just from another update. Sure they can change versions but why not have a setting where you can change to the first textures of Minecraft. Or even add or certain features like new paintings to their game if they choose too, edit how their pvp works or even ambiance sounds. Sure there are mods that can alter Minecraft textures and gameplay, but it would also be caring about the community to already have it in game, in the settings menu.
