If an airplane doesn't fit a traditional navigator's definition of a
boat, then what is it? z/OS is the most recent version of MVS. There's
no reason to expect or want it to fir an artificial academic model.

No. MVS doesn't have a micro kernel, and the BCP runs in multiple
address spaces.
>Does the concept of "rings" or "kernel address space" even exist on
>these machines?
Those are two separate concepts, neither of which is applicable to
MVS. MVS was designed in a more amorphous and distributed fashion.
