I think that would be good advice. Note that even if you're only using
GHC then you still want to use CPP in order to support older GHC
versions which don't support Safe Haskell as in:
Arguably, in that example it would be better to move the check for the
availability of Safe Haskell to the cabal file which would define a
CPP pragma SAFE_HASKELL which can be used in source files.
