How do we want to model dynamic here? Should it have its own special implementation DynamicDeclarationImpl? What about Never?

One idea could be to make TypeDeclarationImpl be instantiable (non-abstract), I don't think we would add any additional fields to it for these. Or, maybe we want a separate interface for these "special" types just to make the class hierarchy a little more logical?

These are special types, I would add DynamicTypeDeclarationImpl and NeverTypeDeclarationImpl.

I think it's probably time to stop minor fixes / improvements to the current API? We have four large breaking changes ahead, we should focus on work that will stay more or less intact through those.

I would be fine with pausing feature work on the existing classes. I think this issue will be relevant though in the new model as well, so we should keep it in mind.

Yes, we can keep the issue for that. Thanks.
