The current NestedNameSpecifier relies heavily on the existing uniquing for
types, so if you are seeing any issues there, they should also exist for
regular types.
For example, non-dependent template specialization types are not uniqued in
clang ever, and also some other types might suffer from this.
Otherwise, can you give me an example of what problem you are seeing?
