Additional context

We should not advertise the setup from that demo as appropriate for production installations, since it relies on a very old experimental Velero patch. Since Velero still does not support cross-AZ, much less cross-region, restores of EBS snapshots to my knowledge, it cannot be recommended. Also this plugin does not work at all for EFS, which is required for HA.
