AFAIU the plan is to separate GHC and its "platform packages", so in
the future it might not be that easy to get to the point where you
_can_ run 'cabal install'.

This is a good point, but to some extent this brings us back to a
discussion that's specific to systems with broken or non-existing
package managers.  Wouldn't it be better to deal with _that_ outside
of HP?
