 Possibly because most of the participants are not that
 familiar with cryogenics ?

 You should note that I did answer, with a pondering that there

 I've some limited experience with using liquified nitrogen as the
 insulation for liquified helium in MRI magnets, but not for using
 as a dielectric gas in RF lines.
