By "after the fact", do you mean it would have been possible to apply to apply the script to a clone which was not working properly? If so, than I overestimated the problem and please disregard.
If not, and the user would have been left with a defective backup, then I stick with my original position. Even if it only impact a few users, the consequences for those users could have been catastrophic.
So, either I apologize or I don't.
