The latter is I think better than the former as CGs can change without the FS

How is cse 2 any kind of problem when using the proper append model?
Except when blk-zoned delays it so much that we really need to close
the zone becaue it's timing out, but that would really be configuration
issue.
As mentioned before, UFS devices implement the SCSI command set and hence do not
support write append operations. If anyone else standardizes a write append
command for SCSI we can ask UFS vendors to implement that command. However, as
far as I know nobody in T10 is working on standardizing a write append command.
