You are correct about the recent change but I think that Apple making the default change exposes a program like ZSH to many tens or hundreds of thousands of people who have no idea what a shell is. I'm sure there are many people around the world who wanted to achieve something on their Mac, found online to open "Terminal" noticed the shell said "Bash" or found something online about Bash scripts, or commands, etc and this leads them down a hole of learning. This can add a lot more than people would think.
