What's the point of using RSC if you have to mark everything as client components?

At best you're getting SSR support since client components actually run on the sever as well, but there are already cleaner solutions for SSR react components that rehydrate in the browser.

You're not using RSC if you're marking everything as a client component. The point is that you can do that and continue to use your old components while also able to use the new app router infrastructure.

Is there that much benefit to just the file structure and router?

That feels like a ton of refactoring just to have the same and result for a user, but maybe I'm missing some important gains of the app directory.
