Maybe we need a stronger culture of Sans-IO dependencies in general. To the point of pointing out and criticising like it happens with bad practices and dark patterns. A new lib (which shouldn't be used its own file access code) is announced in HN, and the first comment: "why do you do your own IO?"

Edit - note it's just tongue in cheek. Obviously libraries being developed against the public approval wouldn't be much of a good metric. Although I do agree that a bit more common culture of the Sans-IO principles would be a good thing.
