On the wiki page you say:

    SPJ: But that goal needs a bit of unpacking. Suppose we divided base
    into six, base1, base2, base3, etc, but each was a vertical silo and
    every other package depended on all six. Then nothing would be gained;
    bumping any of them would cause a ripple of bumps down the line. 

but even if we did just divide base up into vertical silos then I don't
think most packages would depend on them all; for example, most packages
would probably not depend on file-io or concurrency.

But in any case, I'd hope we would also make some horizontal cuts, and I
expect very few packages would need to depend on ghc-io-manager etc.
