You can't make a copy-on-write copy of a file. You can't deduplicate existing files, or existing snapshots. You can't defragment. You can't remove devices from a pool.
That last one is likely to get some kind of hacky workaround. But nobody wants to do the invasive changes necessary for actual BPR to enable that entire list.
Wow. As a casual user - someone who at one point was trying to choose between RAID, LVM and ZFS for an old NAS - some of those limitations of ZFS seem pretty basic. I would have taken it for granted that I could remove a device from a pool or defragment.
