I don't see any real need to add challenge to the meadows after you're multiple biomes past it. These mobs aren't adding challenge. You've already dealt with them in more dangerous forms and numbers before. They just force you to use up good food when you just want to chill out and go chop some wood or hunt some deer and spend all your time dealing with mobs that you can easily handle, but take all the time away from the reason you're there. Its not challenging. No one needs to "git gud". It's just annoying. If you wanted challenge, you'd be in one of the other biomes anyhow.
