The approach of HexOS would be exactly the same as TrueNAS SCALE.
At this point HexOS is a rather watered down, I would even say - dumbed down, UI for TrueNAS SCALE - anything you can do with HexOS you can do with TrueNAS SCALE, it will require a bit more technical terminology.
The promise here is that HexOS should be easier to setup more complex plumbing around the TrueNAS SCALE ecosystem and make overall management simplified - think of an iOS interface vs a Windows one.
We're all in a waiting pattern at this point, hoping to see some change - but it's going to take time.
At this point there is little difference between HexOS and TrueNAS - the only difference is the deck.hexos.com added interface which actually limits what you can do.
