I also don't quite get your complaint... asyncio provides a high-level concurrency primitive with coroutines, and that's a good enough primitive for workflow engines. Even with asyncio you could fork/spawn processes easily with aiomultiprocess[1], if you'd ever want or need to.
What's your use case for having more low-level concurrency primitives (threads/processes) available, having to deal with their synchronization, and running workflows sync?

You'd use asyncio.to_thread[0].
