It's not a matter of simply tweaking the upper bound; with GHC 8 the build fails with

src/Data/CSV/Conduit/Conversion.hs:864:62: error:
    * Expected a type, but `s' has kind `Meta'
    * In the first argument of `Proxy', namely `s'
      In an expression type signature: Proxy s f a
      In the first argument of `selName', namely `(Proxy :: Proxy s f a)'

which suggests that https://ghc.haskell.org/trac/ghc/wiki/Commentary/Compiler/GenericDeriving#Type-levelmetadataencoding may be helpful.
