My experience from playing around with stack the last couple of nights
have been that Stackage is indeed a subset of Hackage packages, but that
it is possible (and fairly easy - if not very documented) to use
packages from Hackage with stack as well. One caveat - depending on how
you look at it - is that you end up specifying these packages with
specific versions in the stack.yaml file for your project.

I personally believe that both a curated subset of "known good" packages
like Stackage and the complete set of packages like Hackage can co-exist
to their mutual benefit. I can certainly see the appeal of stack - I
rather like it so far.
