More World settings

Hi, As a longtime player I think at this point in Minecraft development there should be options to toggle certain features in the world creation menu. For example a lot of players find elytra to be a controversial addition they make many things obsolete. Another example the new health regeneration system and phantoms. I would like to see options akin to don't starve together's world settings. p.s. I think that there are also so many structures in the game now and they clog up the world. their default frequency should be adjusted or there should be an option like disable structures where you can pick and choose what structures you want.
