Tbh, I don't like the "magic" part at all. In fact, I currently rely on `-Wcompat -Werror` triggering an error in my builds. To address the concern more generally is what https://ghc.haskell.org/trac/ghc/ticket/11219 aims to, but without any magic. Then you'd say -Wall -Werror -Wno-error=compat if -Wcompat implied by -Wall. But we ran out of time for GHC 8.0, so #11219 will have to wait till GHC 8.2.
