Wrt USB sysdisks, I suspect part of IXsystems' motivation is selling their own hardware, which doesn't run that way (though it likely could).
Another possible and related reason is they want the sysdisk (OS image, really) to have the same zfs protection and resiliency as the user data -- it's somewhat the same model that the bigger "enterprise" storage vendors like NetApp et al use, i.e. the OS image is kept in the storage array, not on a separate sysdisk (or USB, like we're talking about).
Still, especially for the home consumer market, it seems like a needless omission.
