Why isn't it possible to reinstall TH (unless you also need to depend on
the `ghc` package)? We even explicitly allowed template-haskell to be
reinstallable again in Cabal as there didn't seem any reason to forbid
it anymore (it's no different than e.g. `bytestring` which is
reinstallable as well):
