One can argue it gives better ontology of what is going on, but shifts the burden further into what the pilot wave is. And this actually is far more complicated maybe than QM itself.

Transactional interpretation of quantum mechanics is compatible with relativity and it is it that deserves more attention than Bohm interpretation. Unfortunately it uses a terminology like retrocasuation which sounds even stranger than how Copenhagen interpretation explains QM. So as long as experimental predictions stays the same I see little chances that transactional or similar interpretations will offset Copenhagen mainstream.
