While most hello worlds do not check that the message was printed (which I assume writeStreamingAll does for you), dismissing the rest of the differences as "the others aren't correct" isn't really accurate.
Explicitly passing IO in is a fine design choice, but it's not a correctness issue to say others are wrong to not do so.
