Yes, a matter of philosophy.
For me, absolutely nothing relevant should be on rpool beside minimal storage services. No need for a mirror or rpool backup. On problems reinstall OS to rpool, import datapools and you are again online within 15 minutes after any crash together with a restore option of basic settings from datapool.
Not as strict as SmartOS with a readonly rpool but near to this idea with less restrictions for the global zone.
