+1 Also, given that languages like C# have similar async/await functionality, I'd be interested to know how they address questions like this. If they have a parallel, we should probably follow it. If they don't that would be further indication that no-one has much experience of the "best answers" yet, and caution is indicated. Keeping this open for indefinite time is also not a good option. Note that the issue about yield in comprehensions https://bugs.python.org/issue10544 is 7 (seven) years old. I don't say that we should fix it right now, but I think it makes sense to spend some time and finally resolve it.
