This is cool. So basically you create a group of threads and you can treat them as one unit. Trio does something similar (structured concurrency) with async functions for Python. Are these OS threads or green threads?

They can be OS threads or green threads, you can choose.

Are OS threads still the default and you have to pass a virtual thread executor to use virtual threads?

When you deploy a flow, you choose the workload type (:compute, :io, or :mixed) and the process will be deployed with the appropriate thread type.
