I think that’s a major important point.  Even if the whole of the HPC market were clamouring for it (which they’re not, judging by this discussion) that’s still a very small proportion of the worldwide CPU market.  We have to remember that we in the HPC community
 are a niche market.  I recall at SC a couple of years ago someone from Intel pointing out that mobile devices and IoT were what was driving IT technology; the volume dwarfs everything else.  Hence the drive to NVRAM - not to make things faster for HPC (although
 that was the benefit being presented through that talk), but the fundamental driver was to increase phone battery life.
