That gets you 90% the way there. So, it it only really works if you accept the cruft and the risks associated with that last 10%. Been doing this day in a day out for the last few months and no matter how much and how good we get the automated reviews, we still can't skip the manual ones.
In terms of knowledge sharing and gathering hard-won human context I agree, sort of. An LM review can at least prompt some reasonable changes, catch performance issues, etc.
