That statement is overly negative. The JEDEC Zoned Storage for UFS
standard has been published last week [1]. It can be downloaded by
anyone for free after having created a JEDEC account, which is also
free. As one can see in this standard, nothing excludes using a zone
append command. Once T10 standardizes a zone append command, it can
be implemented by UFS vendors. However, I do not know whether T10
plans to standardize a zone append command.
