Personally I'd use this as a backup target that I could stream ZFS snapshots to. Zpools with the correct level of redundancy protects against bit rot, occasional hardrive failure and the like(as you correctly point out), but not against total machine loss. Its probably helpful to think of it as an offsite backup more than anything else.
