I guess that's what FUSE is for, LOL! Indeed it ZFS does implement this, but none of the block storage impacts or is utilized by anything but ZFS. With btrfs this all has to do with maintaining the legacy way of doing things which is a severely limiting factor. The ZFS devs knew that this would not be a backward compatible change that it's native file system UFS would be able to use at all anyway. They knew that UFS/SFS was not what was required for the next round of storage technology either.
I just think that were were many correct justifications made to do what the ZFS devs did and that by doing so ZFS became a much better product for it. I mean try to understand the btrfs syntax vs the zfs syntax. btrfs is INSANE!
