It's an interesting historical confluence: 8.5's are the clippers of DVMs.
8.5 only makes sense two places: fundamental/high-end metrology
and basic research.
Everybody else are totally fine with 7.5 and very few actually need
more than 6.5 (specifying the temperature of your aligator-clips
gets old really fast.)
The 3458A made it possible to validate the josephson junction as
SI voltage reference -- which ironically made the 3458A surplus to
metrology requirements: Now you can generate any voltage you want
That leaves a theoretical market in basic research, but that's a
very small market which will happily pay a phd-theses for a prototype,
but unless its on CERN scale, production runs are never an option.

Never attribute to malice what can adequately be explained by incompetence.
