I think my point was largely that Windows already has (1) from your list and it's already the gold standard on Windows, and has been available for some 25 years. I would be surprised if it wasn't part of the mechanism used in DirectStorage.

io_uring does have a more ergonomic and POSIX API, but that's because it's on Linux! Fundamentally they're both completion port based replacements to polling for IO events and they're both capable of high throughput and horizontal scaling.

Ok, the misunderstanding here may be that I was using "gold standard" as a superlative among async IO APIs in general, while you're using it as a superlative among a given platform's set of IO APIs, async or otherwise.
