Of course it is not an end goal. But a quarter as much code has (in general, everything else equal) a quarter as much bugs, a quarter of the amount of code to read and understand for new hires a quarter as much code to take into account when adding new features. But none of these things are easy to measure or demonstrate. It is just easier to see that Ma8ee took 1.5x weeks to write 10,000 loc while other developer wrote 40,000 loc in x weeks.
