Comment (by mrkkrp):

 > How is it determined that this build failure is GHC's fault and not the
 fault of say, Stackage or a downstream dependency?

 The build plan we use is fixed, so versions of packages and their
 dependencies cannot change. Any change observed is thus a result of some
 change in GHC.
