Maybe it would be useful if Cabal had some sort of licensing check command that could be run on a .cabal file, and warn an author if any libraries it depends on (directly or indirectly) are GPL'd but the .cabal itself does not have the license set to GPL.
Or are dual-licensed under GPL. That is, the license field in .cabals should take a list or even bool ops, and cabal sdist should utterly fail (as well as hackage) if code that depends on GPL isn't marked as GPL. Note that this is a safety measure for the submitter: If the code is, indeed, released to the public, it is (dual licesed) GPL, anyway, even if that might not have been the intent. -- (c) this sig last receiving data processing entity.
