I agree with what Michael said. Qt labs settings turned out to be a very simple drop-in solution for some basic setting storage we required in an app that we're developing. I had a look at the comparison document, and I also agree that the upstream implementation seems much simpler/more compact. I do not have much experience with U1Db, so I can't express opinion on that end, but I found Qt labs settings to be simple and convenient way to store (at least basic) settings.
I also like the idea that mhall suggested regarding wrapping the upstream component (if that would be feasible).
