Minecraft should have stopped updating past 1.9. If you DO want these changes, add them in via mods. Except Axolotl those dont affect the gameplay loops in any form.
FINALLY, YOU PLAY MINECRAFT AFTER 11 YEARS; NEW TEXTURES, ORES LOOK ODD, MOUNTAINS ARE LIKE A TERRAIN MOD, NETHER LOOKS BAD SO YOU TURN ON CLASSIC TEXTURES, WARDEN, AXOLOTL, DEEPSLATE, DEEPSLATE ORES SO YOU GO DELETE 1.17 AND INSTALL MINECRAFT 1.8
