I agree with this. If there is a need to make it clear that some
features are particularly likely to change, I can't see why that
cannot be achieved in the main body of the report. Through a foot note,
or through a highlighted paragraph of some kind.

I worry that tearing apart closely related topics is going to
be difficult as well as resulting in a confusing and somewhat
unstructured report.

The appendix idea has also been mentioned in other contexts, 
specifically for records, and I don't like it there either for the
same reasons.

Best,

/Henrik
