Executive summary: Microsoft adopted it.  What besides marketing did you
                   expect?

Your idea of variable sized memory pages appeals (cf the small, normal
and large I/O request packets (IRPs) used by VMS)

P.S. I looked shibboleth up because I wasn't entirely sure what it means:

noun
a custom, principle, or belief distinguishing a particular class or group
of people, especially a long-standing one regarded as outmoded or no
longer important
