I think the change is correct and required in general.
cabal-install-0.14.0 warns if there are reverse dependencies of
reinstalled packages, because these might be broken after the
installation process. If the set of potentially broken packages is
non-empty, it implicitly adds -v, because without it, the user won't
be able to see which packages are reinstalled. I'm sorry that this
causes problems for you.

Cheers,
