The whole idea of Bohmian mechanics is to preserve the notion of « classical trajectory » while trying to cover existing experimental evidence for QM. I was a fan of it ant the University - but slowly realised that the strategy seems to be just add the classical-limit consequences of the QM as extra postulates. And even that approach faced larger and larger obstacles - like fermions statistics, the QFT with creation / annihilation of particles, spinor fields requiring Grassmanian « classical trajectories » and the whole thing still requires preferred reference frame - in obvious contradiction with basic SR.

This whole story is very similar to attempts of physics fringe to preserve the notion of « aether » while satisfying the experimental evidence for SR.
