Per https://github.com/tc39/proposal-async-iteration/pull/102/files: AsyncGeneratorResolve no longer unwraps a value component. Instead, the value is unwrapped before the builtin call via Await, allowing Promise rejections to affect the generator control flow. Thus, all `yield <expr>` implicitly become `yield await <expr>`. Additionally, `return <expr>` becomes `return await <expr>`. Finally, when the generator is resumed with `.return()`, the parameter passed to .return() is awaited before generator execution properly continues).
