For example I work with a codebase like this. It is over ten years old, have multiple people working on it, many learning or of differing abilities. Frameworks have been used and over time their limitations come to light. Often people have been band-aided something to save time, because they have been under severe time constraints. Large swathes of it are almost superseded but not quite. The purpose of the software has subtly shifted over the last decade.
