The notification/callback approach where the event loop is given a chance to intercept the first iteration of any given coroutine seems nicer to me, since it opens up more opportunities for event loops to experiment with new ideas. As a very simple example, they could emit a debugging message every time a new coroutine is started. asyncio could provide a default notification hook that just mapped weakref finalisation to asynchronous execution of aclose().
