I agree with Martin.  We can try to avoid the issue  (and usually people
should to make backporting fixes easier), but adding that hinderance can be
a real pain, especially as we get farther and farther away from 2.3 .

I think it is better to add a comment in the external release that it is
backwards compatible somewhere, but leave it out of the core.
