World and Structure Exporting/Importing in Minecraft Pocket Edition

Why don't you just add the world and structure exporting and importing button in Pocket Edition? Don't you respect people who want to add a way to export worlds in mobile devices? Don't you respect people who want to make maps in their mobile devices? Don't you feel sad for people who lose their worlds after they change devices? Everyone is trying to make a method to export their worlds and structures and Mojang Studios is just ignoring these people.
