An interesting mind binder is if one makes ASIO's async_result 
vtabled i.e. a listener class.

That would make async_result ABI stable, and eliminate most of the 
rationale for improving futures, arguably even the present approach 
by Microsoft and the committee on how to do resumable functions.

I am personally surprised that Chris hasn't proposed this yet in one 
of this N-papers proposing the ASIO way of doing async instead of the 
current approach by the committee :)
