I'd go even further that the modern problem with modern Minecraft isn't the fact that they're adding new mobs or items it's the fact that Minecraft originally felt like it was inspired by old school RPGs with random mods vaguely fitting that aesthetic and now modern Minecraft just seems to be chucking in random real world animals well occasionally throwing in random fantasy creatures they made up.
I think the reason why that one Minecraft mod which is called "better than adventure" feels so authentic and real because it's inspired off of the idea of old dungeon crawling aesthetic
