Neutrino Oscillations evolve with Redshift ?

[Widdekind]

According to the Borexino Princeton Group, Neutrino Oscillations behave differently, in high density media, at high energies:

 

That complication is the Mikheyev-Smirnov-Wolfenstein (MSW) effect, which results in what are known as "matter oscillations." In very dense matter such as that found at the center of the Sun, neutrino oscillations work differently, because the probability that a neutrino interacts with the surrounding matter is no longer negligible. High-energy solar neutrinos such as those seen by SNO instead act like electron neutrinos with a probability of about 31%. It is only low-energy neutrinos that behave according to the "vacuum oscillations" giving a 57% electron neutrino survival probability. So neutrino experiments such as SNO that have a high energy threshold see electron neutrinos with a 31% survival probability, whereas experiments that can see nearly all neutrinos (99% of which are low-energy), such as the GALLEX and SAGE radiochemical experiments, obtain the 57% value.

What effects would this have had, on Neutrinos, at ultra-early epochs, at ultra-high red-shifts, associated with Primordial Nucleo-Synthesis ?

The idea of the paper is speculative but now based upon much evidence. But as to neutrino interactions with matter effecting/ evolving redshifts, I can think of no possible mechanisms how this could happen. What is your idea?
