Disagreed. Better "-3" warnings could make porting easier. (Not just
more warnings -- "better" might mean fewer false positives for
warnings already issued.)

FWIW, it doesn't sound like killing 2.7 is a productive thing to do.
However making 2.7 the end of the line (though with indefinite bugfix
releases) might be. (Indefinite != infinite.)
