The T10 and T13 standards have been updated with some features like SATA autosense which requires changes to the various subsystems and the implementation itself. These features would also allow for a simpler ZBC implementation, but would require a more in-depth analysis of the filesystem behaviour. Additionally the zone model has been modified, which would require some changes to the block layer when formatting the I/O. Also I'd like to discuss if and how generic filesystems could be supported on ZBC drives.
