It was exactly the first thing that came to my mind when I saw the
change to the Makefile in the patch.  Unless our breaking changes
are all removals, which is not likely to be the case in the longer
term, "without-breaking-changes" would be an invitation for
confusing double negatives.

The above parts of the documentation getting commented out all look
sensible to exclude in a build that omits these older mechanisms.
But can we do it with !with-breaking-changes instead?
