Keep all core Minecraft commands and selectors permanently

Please keep all core Minecraft commands and selectors permanently. Commands like /fill, /setblock, /clone, /execute, /summon, and /tp are essential for building, automation, education, and mapmaking. Selectors like @p, @s, @r, @a, @e, and @n are required for command block systems. Removing or limiting these would break many worlds and long-term projects. These tools are a core part of Minecraft creativity.
