Don't get me wrong here. I just meant to diff two rpms in a way, were
you take apart the two rpms diff their content, (including _all_
metadata of course) put the diffs in some kind of container (prpms?).
Then, when the end-user would update the old installed rpm would be used
in conjunction with the diff-container to produce a new current rpm.

Maybe my point was not clear because I also mentioned single files on
the end-users computer. What I meant there was, you could recreate the
old installed rpm out of data mostly already present on the end-users
computer, instead of having to keep a copy of the rpm around.
