I disagree with your retraction of the page 9 comment.
The only way an error is returned is if the second equation in 4.3.3.op.6.3
Select a sequential write required zone evaluates to true. If the values in
the equation are spelled out, the following must evaluate to true:
the number of sequential write required zones with a Zone Condition of
the contents of the MAXIMUM NUMBER OF OPEN SEQUENTIAL WRITE REQUIRED ZONES
field of the Zoned Block Device Characteristics VPD page
Now, if there is so much as one sequential write preferred zone open, then
the zoned device is not allowed to support any sequential write required
zones. Therefore, the number of sequential write required zoned with a Zone
Condition of EXPLICITLY OPENED must be zero.
Surely, zero should be a small enough number to be less than any valid
contents of the MAXIMUM NUMBER OF OPEN SEQUENTIAL WRITE REQUIRED ZONES field,
All the best,

I just realized that I introduced a bug in 15-113r4 as modified.
On page 9, I commented "All zone management operations to sequential write
preferred zones return successful completion". However, in the case where
there are no implicitly opened zones available to be closed (i.e., all open
zones are explicitly opened zones), the zone management operation will indeed
return a non-successful completion.
I will have suggested text to correct this later today.
