This is how some other targets do it, grepping grep ^W config/*/*.opt (a bit noisy because of descriptions). config/gcn/gcn.opt:Wopenacc-dims config/gcn/gcn.opt:Warn about invalid OpenACC dimensions. config/i386/mingw.opt:Wpedantic-ms-format config/i386/mingw.opt:Warn about none ISO msvcrt scanf/printf width extensions. would be not Target but config/rs6000/darwin.opt:Waltivec-long-deprecated uses Target (and thus is dysfunctional) So it seems we're not set up for 'Target' warnings.
