-Assume anything could still change, but limited change should be expected.
-This draft specification will change before being accepted as standard, so
-implementations made to this draft specification will likely not conform to
-the future standard.
+Change is extremely unlikely. A high threshold will be used, and a change will
+only occur because of some truly critical issue being identified during the
+public review cycle. Any other desired or needed changes can be the subject of a
+follow-on new extension.
