My point is: is there even an unusual case in that it could be useful to
have cabal-install installed and not ghc6?

By the way, this quote made me remind of the discussion about -doc
packages relationship.  I can think of unusual cases in which one would
want to install a -doc package with broken links, to avoid having to
install all the -doc stack, for instance, when a user wants just to
check the doc of a specific package and remove the package some minutes
latter.  So, reading this quote, I think Recommends is the way to go for
-doc packages.

Thanks for answering.
