My personal suspicion is that a lot of preexisting codebases are running on inertia. The abstractions exist and are used well so the generated code also uses it most of the time, with only occasional breaks to the abstraction that look like an acceptable tradeoff in isolation. But those would keep piling up to where the existing abstraction is no longer so identifiable and that's where the major spaghetti code issues start happening.
