On a happy note, this update finally fixed a small issue I was having with my P1006 (where photos would print as if somehow magically down-sampled to 32 or 24 colors). Huzzah.
For simpler, third-party apps, I just make an archive of the current app and any prefs (although that file seldom changes) BEFORE installing the update. If things "go south" all I have to do is delete the new file and un-archive the old on. It's usually much, much more difficult to to use this method for SU stuff, files could be being updated all over the OS... ;-)
