I've heard it said that measuring productivity of a software developer by lines of code added, is akin to measuring the productivity of an aerospace engineer by mass added.

It is a metric. It is often not a good metric. But it is easy to measure.

Indeed. The more you do to add complexity or generate without ensuring it isn't pointless code adds bloat. It is still probably more MVP than junk developers will do, but not ever anywhere near as great as someone who studies a programming language.
