  As it is suggested in \cite{Sakstein:2019fmf, CarrilloGonzalez:2020oac}, one
can dynamically introduce the coincidence time-scale for EDE in the framework
of a particular mass-varying-neutrino-model as a time at which neutrinos
constituting the cosmic neutrino background enter the non-relativistic regime.
The model does not predict, however, the right amount of EDE density because of
smallness of neutrino masses. One may hope to adjust the parameters in such a
way as to ensure that the two-loop contributions are kept small while at the
same time the effective mass for scalar field that enters the expression of
zero-point-energy (for the field trapped in the minimum of effective potential)
is sufficient for explaining the needed amount of EDE. Unfortunately, the
answer is not in the affirmative.
