I don't follow how it would work better. Right now I don't need to do any kind of setup or thinking. I could rewrite a huge chunk right now as an experiment and change 1000s of lines of code. Then if I don't like it I can just press "reset" and I'm back to stable. In fact, I did just that yesterday.
