I work on a codebase of 16 millions lines of code. In general it's a relatively good codebase, but it's far from perfect. Some things are easy to refactor, so we try to do it. Some other would require big architectural changes. Sure, I would love for the product to be perfect, but perfect evolves with time, and the codebase is 35 years old. You just have to live with imperfect code.
