No you don't, not in the Twisted case. The fact that useful library routines
return Deferred objects to which you add callbacks and errbacks is probably not
going away, because it's a fundamental building block in Twisted, not a
convenience for scheduling generators.

As a matter of fact, the people whom this PEP is supposed to benefit haven't
expressed a lot of enthusiasm right now. That's why it looks so academic.
