Spot on. This is what Durable Functions does on Azure and it's brilliant for implementing complicated business processes and handling multiple events in one flow, in a resilient way where the logic is easy to follow.

One catch is that you're going to have to version your code if your workflows/orchestrations run for days, or if there's no windows without running workflows. And there's no built-in support for this, so expect to duplicate your entire workflow for new versions, so the old one can run to the end with the old code.
