That are exactly the cases I'd like to catch.

During package development sometimes it's necessary to make some
modifications (or change entire file) in /usr tree for testing purposes.
When you forget about it and upgrade package these changes are lost.
Recently I've found old file (this time causing problems) and
I can't recall replacing it. Now I'd like to review entire repackage
spool for modifications done before upgrade.

There would be differences in config files and missing languages for
sure, however other permissions, timestamps and modifications are worth
pointing out.

Nice feature, too.
