Skimmed the paper briefly. Looks like reformulation of single-particle QM with no new predictions. Most importantly (and as I mentioned above) doesn’t address particle creation and annihilation, which is where Bohmian-style approaches usually struggle.
Authors seem to be aware of that, but make a weird tap-dance around the problem throughout the paper, seemingly scared to even "Voldmort" it. In that context, citing 1930 Dirac paper is laughably ironic.
