I snapshot boot, root, and home together. In almost any likelihood of a rollback in a bad system update, I'd keep the existing /home rather than rolling it back. But in case of a wrongly delete file or pile of emails, it's useful to also have /home snapshots.

Ideally we'd have snapshots of /home happening much more often, like on a schedule every hour or every day. Whereas with boot and root subvolumes, they only need snapshotting immediately prior to a system update.
