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
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.
