I discovered this today and was quite surprised, so I thought I'd share.

You can obviously do a full reset and then use Migration Assistant on a backup. This might take a half hour and it's a hassle.

But you can also boot into recovery, go in "Restore from Time Machine", pick a recent snapshot (including hourly "local snapshots"), and roll back to it. It takes seconds (and a reboot) and your Mac is now rolled back to its previous state.
