I think that the problem of forgetting 'yield from' is a bit exaggerated. Yes, I myself forgot 'yield from' once or twice. But that's it, it has never happened since.

I think it's more likely to happen when you start with an ordinary function, then discover that it needs to be suspendable, so you need to track down all the places that call it, and all the places that call those, etc. PEP 3152 ensures that you get clear diagnostics if you miss any.
