I use them constantly in my work on Orchid, and, FWIW, one of your coworkers--Lewis Baker--was seemingly hired to help champion the standards and work on Folly Coro. I use the feature much the same way I would in, say, JavaScript (doing stuff like "await Fetch(...)" or "await Query(...)"); I honestly am sufficiently confused by your question that I am having a hard time saying much more... the C++ version of this primitive is great because it doesn't have any baggage about "executors" or anything and lets me have complete control over how the task switching happens. You can build generators with the feature, but I almost never do; there are a couple things I wish the C++ people had done with their implementation (which involves a weirdly thick-feeling interface to implement, and which makes it difficult to truly avoid memory allocation)--in particular, including some of Lewis Baker's interests in asynchronous deconstruction, without which I am finding myself often boxed into a corner (though what I really want, honestly, are true "linear" types)--but by and large I love the C++ implementation of this for its complete flexibility.
