Maybe it technically falls under 'restore from backup', but OpenSUSE comes configured to create BTRFS snapshots before and after every package manager operation. Since this excludes the user's home, the effect is that you can rollback an update quickly without losing any work. I think this sort of system would work well for MacOS/Windows/etc, but perhaps it would give the users a bit too much power than these companies prefer...
