And it's really expensive, despite your suspicions.
We figured out that LOC was a useless productivity metric in the 80s.
Microsoft paid my company a lot of money to write code. And in the end you were able to count it, and the LOC is a perfectly fine metric which is still used today to measure complexity of a project.
If you actually work in software you know this.
I have no idea what point you're trying to make - but I've grown very tired of all the trolls attacking me. Good night.
EDIT: OH. You mean that people don't cite LOC in contract deliverables. Yeah, I know. I never said that, and it's irrelevant to my point.
