John,

Regarding the "ordered" a,b list... Although much of the motivation is 
beyond what my aging grey matter can fully comprehend, I am under the 
strong impression that the "ordered" list can only be corrected by 
adding an additional entry:

    "c) all of the above"

Thankfully, my meager efforts in T10 are buttressed by a multitude of 
experts in a wide variety of storage technology, operation systems, and 
mobile devices.

With respect to the "mobile focused device feature optimization (largely 
used for Flash technology)" observation... Perhaps it would not be 
talking too far out of school to note that:

  * NVMe _is_ optimized for ... Flash technology; and
  * NVMe Zoned Namespaces /(kissing cousins of ZBC-2 devices)/ are
    intended to improve the performance of support for Flash technology.


In summary, there seems to be a very good possibility that you are 
chasing the right rabbit down the right rabbit hole.

All the best,

.Ralph
