Well, yum is being retired in favor of dnf and btrfs still isn't the
default filesystem because it still isn't stable enough.  So that's
basically what happened.

Now, it is possible to do this in dnf (either with btrfs or with dm
snapshots) but I'm not aware of anyone working on it.  Fedora has the
Snapper tool available in the repos, which could do snapshotting
outside of dnf as well.
