I’ve seen this in two broad circumstances: complex business rules, and spaghetti code. Business rules mostly have to be endured. Spaghetti code should be untangled if the software is still actively developed. This caveat appears much less often in editors, design applications, general horizontal apps and games. Those are more likely to suffer from poor design or coding, and the spec is much more in the control of the software people.
