One of the ideas that came up in a recent discussion about wanting to be able to delegate (or authorize) third parties to act on and interact with our rosters was that if we had a "perfect" rollback solution that wouldn't be so bad. That got me thinking about the new roster sequencing XEP, and how if it supports labeling changes, then we could use that tool to label those changes as being made by a delegate, and rollback those changes as we see fit.
This of course totally ignores the fact that we don't seem to have anything close to a delegation solution, but i thought it might be good to bring up that possible unforeseen use case up. ~ Anders
