What exactly are you talking about with "parameterizing field" and a couple comments up and "the lambda-cdm field" (emphasis yours) ? Are you referring to the Friedmann equations? The equation of state? The half-dozen free parameters of the model itself? What's your exact objection here? Because there isn't anything that I would quickly call a "lambda-cdm field" in the standard model of cosmology any more than there is a single "standard model field" in the standard model of particle physics. "The field itself does" -- again, what exactly do you mean here? Are you even talking about a mathematical or even physical object?
