(and no, adding things like nonlocal to 2.7 doesn't making porting of a real application or library any easier, since the existing application or library simply doesn't use that keyword.

Agreed.

In fact, no change to 2.x can reasonably simplify porting - only changes to 3.x might - except for changes to 2to3, which can simplify porting a lot. But 2to3 should be run under 3.x, IMO.)

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.)
