Versions: Possibly anything under 1.20.1

I was playing around with snow golems when I found that, despite the fact that Iron Golems don't fight Creepers, Snow Golems do. This is a major issue, because houses could be exploded because of Snow Golems and Creepers. I'm not sure if this is new or not, but I just found this out. Minecraft version I'm using: 1.20.1
