I guess GvR expects Twisted, Tornado et al jump on the asyncio
bandwagon.

Myself, I would like the lowest-level I/O transactions to be broken into
their atomic, nonblocking primitives:

    request       optional: update(s), cancellation
    response      optional: preliminary response(s)

Those primitives can be then used to put together asyncio coroutines or
blocking functions for multithreading. Or they can be used as-is in
classical callback programming.
