Nope, the system would instantly panic - presumably in order to protect data integrity... imagine the damage possible otherwise. It was actually a fairly ponderous debugging effort, as I remember it, because it was occurring on an already shaky POWER9 setup I was using to port other stuff. ZFS worked great for any vdev setup on any OS compiled with the same endianness, but plugging in so much as a thumb drive previously provisioned from a different endian host... insta-console-vomit. Definitely an uncommon problem though :)
