Other than the fact that code - both initiator and target - has already been
written to the VPD page implementation, there is the inference that material
in the REPORT ZONES parameter data may be dynamic, while VPD page data has
the implication of being static.

Based on the ZBC interface simplification ideas introduced for the REPORT
ZONES command in 14-212 (see
http://www.t10.org/cgi-bin/ac.pl?t=d&f=14-212r0.pdf), some WD engineers have
asked whether additional reductions in complexity might be accomplished by
moving the contents of the Zoned Block Device VPD page to the amply spacious
header of the REPORT ZONES parameter data.
To this end, a detailed proposal has been uploaded for review during Monday's
ZBC call:

All the best,
