I don't think you can honestly claim "full backwards compatibility" as long as there are some combinations of old-style and new-style code that won't work together. You seem to be using your own personal definition of "full" here.

Well, using next() and iter() on coroutines in asyncio code is something esoteric. I can't even imagine why you would want to do that.
