Huh. Indeed, that "Next Steps" page never has been created. That's an excellent suggestion, thank you. I just opened up https://github.com/reactjs/redux/issues/2626 to cover adding that docs page.

If you or anyone else reading would like to contribute writing that page, please leave a comment and let me know!

And yes, it's always tough to balance the various audiences and use cases when writing docs. Minimal examples like a TodoMVC can be helpful for showing off basic concepts and keeping a learner from getting too lost, but then those don't cover the complexities of a real-world app.
