It seems easier to copy data to a new ZFS pool if you need to remove RAID-Z top level vdevs. Another possibility is to just wait for someone to implement it in ZFS. ZFS already has top level vdev removal for other types of vdevs. Support for top level raid-z vdev removal just needs to be implemented on top of that.
Cool, just have to wait before it is stable enough for daily use of mission critical data. I am personally optimistic about bcachefs, but incredibly pessimistic about changing filesystems.
