Hi Dan, nice to meet you and many thanks for the interesting comment.

Why do you think that we should be able to reference a Coordinator by a string? What use case are you looking at?

Stringification is usually something we would like to avoid. It is error-prone and the compiler can't help us if we pass a bad string. So I'd personally avoid such an approach.

For the second part, I think it depends on the specific application. If you have that need, you can keep a reference to the RootCoordinator in the AppDelegate and use it to respond to a deep link for example. But I won't add features that are not necessary and those specific use cases are slightly out-of-scope for this article.
