Original author here. I do think it’s good to think about rollback strategies (especially given that your change might go out with something else that might need rollbacks). There is one thing though, and that is that a lot of these transformations end with more information, so you can usually recover the old state if you ever needed to (or write some compatibility shim for whatever reason) I had a whole part about rollbacks (and an intuitive proof about why each step was needed and not being able to skip any) in my notes for this, but I decided to leave it out cuz I couldn’t do it justice just yet. There are so many little details to cover in this space, and honestly the vocabulary and tooling are a bit poor so it’s hard to be succinct
