 While, as argued above, it appears plausible that decoherence might be instrumental in recovering the classicality of pilot-wave trajectories in the case of the non-relativistic particle theory, it is less clear whether this strategy might work equally well in the case of field theory. Doubts to this effect have been raised, e.g., by Saunders (1999) and by Wallace (2008, 2012b). Essentially, these authors doubt whether the configuration-space variables, or some coarse-grainings thereof, are, indeed, decohering  variables.[28]
