I’ve worked in big companies and I’ve worked in small companies. The one constant has been that writing code is required to make product changes. No code likely means no changes. Maybe LOC != productivity makes sense when algorithms are of great importance, like in situations where a genius algorithm can unlock tons of value. Machine learning would be one example. However, most work is feature work, which typically has a straightforward path from start to finish. In product feature work, it’s unclear to me what activity would use time productively that didn’t result in lines of code.
