Well... The only question should be architectural:

- why automatic, silent upgrades

- why no boot environment/generations at boot to reboot into a previous snapshot of the system (since nfts do have snapshots indeed), meaning why no integration between the storage and the system management

- why massive rollout instead of partitioned testing rollout slowly propagating

For the rest is a third party tool, not mandated by the vendor so... It's a user choice.
