Of course not. But reality sets in at a certain point of software
complexity- # of bugs/kloc doesn't grow linearly with code size, it
grows exponentially. So, yes, obviously, customers don't care how large
it is. But multi-million LOC GUI apps are not the same as Hello World,
no matter how you slice it. It's just Really Fucking Hard to do right.

It does say something about complexity of the product, even if it is
only a first-order approximation.
