I don't think that's accurate.
Which part? OSTree doesn't require either LVM thinp or Btrfs. It works on plain ext4
OSTree doesn't touch /home from what I
remember. It is only concerned with /usr and to as minimal a degree
as possible /etc. People likely still want snapshot and rollback for
their actual _data_ as well.
Orion didn't mention /home, and Roller Derby doesn't directly address it either.
Both yum-plugin-fs-snapshot and snapper can, but snapshots coincide with system updates.
More useful is a regularly timed snapshot of the user's home, .e.g. hourly with age
