Relativistic extensions aren't pleasant in standard QM either. Bohmian formalism would require something perhaps no less aesthetically repulsive, but surely more alien: a preferred foliation of spacetime to avoid a preferred reference frame. Turns out it wouldn't have to be an artificial choice, as it can be derived from the wave function itself https://arxiv.org/abs/1307.1714 https://arxiv.org/abs/1307.1714 (that would also mean this preference existing within QM irrespective of any interpretation).
