And also, I asked someone who works on the FW about these IR concerns and he says the only reason for a performance issue is that the IR FW is a bit larger and therefore the command queue depth will be smaller due to the amount of resources available, so it is possible to have a slight performance degradation in some cases. Other than that, once it is determined that there are no IR drives the FW acts just like IT. AND there is no data corruption issue for ZFS disks. If there is, that would be bad and a high priority defect would need to be filed :) If there are no IR volumes, the FW works just like IT so there would be no reason to write metadata to a non-IR disk. Even if there was a separate IR volume, the ZFS disk would not be written with metadata because it's not part of an IR volume.
