What's the reason that data classes `copy()` and `componentN()` are now returned in `KSClassDeclartion.declarations` when <https://github.com/google/ksp/blob/main/docs/ksp2api.md#synthesized-members-of-data-classes|using KSP2>?

I'm sure there's a very good reason for that but my mental model has always been "declarations are something that is present in the source code". In a way I always pictured KSP working mainly from the Kotlin AST but looks like it's not the case? How should I update my mental model?
