I don't think that's the spirit of that blog you pointed out. Redis is quite different from traditional databases. And so things work differently and some features may be important in RDBMS, might not be that useful in Redis because of how different they are. I think the blog talks about that in two sections. "First reason to use rollbacks: concurrency" and "Second reason to use rollbacks: leveraging index constraints" says why it's different in Redis. Going back to the car analogy, if you are an electric vehicle, some things are completely obsolete when compared with gasoline vehicle.
