Well the article suggests that the new feature can "be used to roll back an
unfortunate upgrade without taking the system down"

But needing to unmount the root file system seems pretty much like "taking
the system down" to me. In other words, nothing fundamentally changes, it
just got more convenient.

That's a fairly major improvement in convenience though. I for one would welcome this very warmly after my LVM escapades a couple of weeks ago.
