Using 512b for 4k devices will cause performance degradation because of the read-modify-write that the hardware = will have to do for every 512b write. I don't think it makes sense to locally modify the behaviour of ZFS in this instance. Hopefully we will eventually get the "Time Variable Geometry" feature for Z= FS that will allow all future allocations to be made 4k aligned, even in the f= ace of pools created on older versions of FreeBSD where we didn't have quirks in place on some disks that lie about their sector size. Video and Slides about the feature.
