I would love to see this issue tackled. I think the tough part is, how do you update the span processors to know if they have a sync or async exporter? I think it would also be useful to have an AsyncBatchSpanProcessor which replaces the background running thread with an async task

I agree. The next step would be to define an async span processor. You're welcome to join the effort. It'll be quicker to implement this way.
