My point of disagreement is giving the mainstream view as "the wavefunction is the fundamental description of reality". I claim that the mainstream view, as seen in type 3 theories, treats the wavefunction as a mathematical object, not a fundamental (i.e. physical) one. For example, Griffiths (who introduced consistent histories) describes the wave function as "a mere mathematical tool or pre-probability for calculating probabilities which can, if one wants, be obtained using different solutions to Schrödinger’s equation." He goes on to contrast this to MWI and Bohmian mechanics, which treat the wave function as fundamental, are both deterministic, and are minority viewpoints.
