The original proposal for introducing 'yield from' (which is still in PEP 380's name) was to delegate a part of generator's work to another generator. However, in later discussions, the focus totally shifted to cooperative multitasking.
I still regard delegation as an important use case for yield-from. I haven't dwelled much on delegation of plain value-yielding generators in my examples because it seems rather obvious and straightforward. My coroutine examples are meant to show the motivation for some of the less-obvious aspects of yield-from, such as the ability to return a value.
I won't pretend to understand the current discussion or its motivation, but I know I would appreciate it if examples of the obvious-and-straightforward variety were added.
