“Ideal use case” such a wild take. The “10%” (assuming you mean all the issues pointed out in the article) are the things that take the most time and effort to do (or fix now), which you can’t do without understanding and fixing the “90%” of “translation”.
You simply pointed out that challenges remain in what the other poster said is otherwise the ideal use case, which was his point. What is the ideal use case in your opinion, since you disagree?
