That experimental datum suggests several things.
(i) all materials at a cold enough temperature are superconductive and if
so, then superconductivity is a Classical physics phenomenon
Please think about what you're saying. "All" is a mighty big word. Does
sapphire superconduct or quarts or any insulators at low temperatures
and normal pressures?
You are arguing with a psychotic idiot troll who is trivially
gainsaid.
1) Bose-Einstein condensates operate at nanokelvins. No anomalous
superconductiviy has been observed. The Meissner effect would be
trivially detected.
2) Liquid helium will stay liquid right to absolute zero unless
compressed to at least 25 atmospheres. We can say with complete
assurance that liquid helium under its own vapor pressure will not be
an electrical superconductor at any low temperature - right down to
absolute zero in the limiting case. There will never be a solid
lattice whose phonons promote Cooper-pairing (much less free electrons
to be Cooper-paired).
