A fearful user downloads new packages and performs a test upgrade on a
test machine.

A fearful user knows that any shiny new version upgrade may lead to severe
regression, brown paperbag bugs, and other defects, regardless of how
upstream advertises the NEWS in their doc files.

If you mix upstream ChangeLog details and packaging %changelog details,
you create a blurred picture of who did what. Further, some upstream
developers are very verbose in their ChangeLogs, so as soon as you
started trying to sum up the changes in a new version, you would either
fail or end up copying the entire ChangeLog into your spec file.

In general, let users assume that a version upgrade is bigger'n'better
unless it failed during your packaging QA.

The majority of end-users are not interested in implementation details in
developer ChangeLogs unless they are confronted with run-time
misbehaviour. And even then, many of them don't read ChangeLogs to find
out which CVS commit may have been the culprit.

This belongs into the "spec %changelog should [...] cover important
changes in the packaging" as an incompatible version upgrade means that
you need to put a warning into your %changelog because _you created_ an
_incompatible package_.
