I think it really depends on how the warning is enabled. I don't think it
should be part of -Wall, but I could see it being there for people that
want such things. And if you're going that route, shouldn't it be part of
hlint instead of ghc?

So, I think I just convinced myself that I'm -1 on this too :)
