Have you tried how rpm reacts to a %config(noreplace) for those files ?
I am not sure how it deals with file deletions, but for files changed by
the user, it properly creates the new file as .rpmnew (and some people
actually have scripts to help them reconcile the rpmnew files with their
changes, interactively, of course)
