Arguing about a wavefunction being real vs just a representation doesn’t seem to initiate religion in the bad sense even if one argues that the wavefunction is real. Such people would still propably agree on the practical consequences for experiment setup. The focus on the argument seems to be about people for the “abstraction users” that have different practical outcomes. The criticism should be in that the transformation is wrong rather than using a transformation in the first place.
