This looks really awesome! We were just discussing at work how we're having a hard time finding a framework for a task queue that supports dependant tasks and has support for Python & TS. I suppose writing that out it does feel like a pretty specific requirement. I'm glad to see this pop up though, feels very relevant to me right now.
A question around workflows having just skimmed your docs. Is it possible to define a workflow that has steps in Python and a TS app?
