I couldn't come up with an example where StopAsyncIteration
would have same "bubbling" problems as StopIteration (I tried
to).

If someone can come up with a good case that would definitely
trigger more thinking about that.  FWIW, there is a PEP
implementation, so it's possible to explore and prototype.
