It is the master and decides when snapshots should be deleted. Proxmox also has a schance to quisece the VMs and so the snapshots will be application and not just crash-consistent. This is a cleaner experience for the VMs and users. TrueNAS will just take, list and delete the snapshots efficiently based on plugin and API request.
