Code requires maintenance, which grows with codebase size, minus some decay over time. (LLMs do not change this, and might actually be more sensitive to this), So increasing code size, esp with new code, implies future costs, which meets the definition of a liability on a LOC kinda-sorta-basis.

It's not right but it's not wrong either. It at least was a useful way to think about code, and we'll see if that applies in LLM era.
