I never said it was. To the contrary, it's more of an indication of how much more complex large refactorings might be, how complex it might be to add a new feature that will wind up touching a lot of parts, or how long a security audit might take.

The point is, it's important to measure things. Not as a "target", but simply so you can make more informed decisions.
