Why would I want to do I/O, when I don't know how to do anything
interesting with the input yet, or how to generate interesting output?
I think the `I/O comes first' attitude is *precisely* the difference
between mainstream programmers and Haskellers. The goal should be to
create more Haskellers, not just more people whose code happens to be
accepted by GHC.

That short, and you expect minor features like that (that not every
program even needs) to be squeezed in?
