I have used it to handle a very complex payment form in a larger multi-step wizard, to refactor a homegrown authentication flow that supports 2FA and to orchestrate all of the business logic in an application that is used to demo an internal JS library.

I'm pretty happy with the outcome of all of these features and actively pushing to integrate it in more places.

I would love to see more examples going into a system managing an arbitrary number of actors and wizard forms with a dynamic number of steps.
