That is the equivalent of saying that the direct expression of a musician‘s work are the sounds they produce and therefore they should be heard in isolation.
But as much as an orchestra produces symphonies as a group, development teams produce software as a group. This output matters and should be looked at, the individual code contributions to that output matter less and looking at them in isolation doesn’t provide insights that looking at the team‘s output in terms of working software, bugs, incidents and more wouldn’t.
A manager looking at the individual LOC contributions is looking into the wrong direction.
