I was thinking Mojang could actually add a whole new game mode in the major update after 1.17. My idea was that they could add a mystery game mode where they make an auto-generated mystery (Missing Villager, disappearing stone, etc.) I really hope Mojang adds this thanks! Another idea is a diamond compass you could craft with nine diamond blocks (81 diamonds). This may seem overpowered but after all 81 diamonds is a lot! Thanks again!
