Just wanted to mention / record the case of std::time_get which has an
additional virtual function (do_get) in C++11. I don't think it affects
in important ways the points you are making.

As long as the new virtual function is at the end, it would only affect classes that derive from std::time_get in a multiple inheritance context. But to be safe we could bump the time_get ABI as well as the others.
