I don't really know Config::Model. But the main problem I have with the
current system is, that I only see diffs between the currently
installed version and the new package version. 

No what I really would like to see is the diff between the last version
I've merged and the new package version. So changes can easily be seen
(changes in defaults, new/removed parameters or just white-space
changes?) and merging would work without a conflict in most cases.
Similar to like SCMs work.

Config::Model could be useful in addition, but would it support such a
work-flow?

Cheers,
