The future for de Broglie–Bohm theory doesn’t look overwhelmingly bright:

Here we show by both theory and experiment that a broad and rather reasonable class of such non-local realistic theories is incompatible with experimentally observable quantum correlations. In the experiment, we measure previously untested correlations between two entangled photons, and show that these correlations violate an inequality proposed by Leggett for non-local realistic theories. Our result suggests that giving up the concept of locality is not sufficient to be consistent with quantum experiments, unless certain intuitive features of realism are abandoned.
Add this to Bell’s own conclusion in 1964 (my emphasis):

VI. Conclusion
In a theory in which parameters are added to quantum mechanics to determine the results of individual measurements, without changing the statistical predictions, there must be a mechanism whereby the setting of one measuring device can influence the reading of another instrument, however remote. Moreover, the signal involved must propagate instantaneously, so that such a theory could not be Lorentz invariant.
Then we have to reject Einstein, SR and RoS + the physical experiment by Anton Zeilinger + introducing a global NOW (that we know doesn’t work in e.g. GPS satellites)...

It’s not the non-locality in itself that brings 'problem'. It’s the fact that Bell's theorem proves that nature at microscopic QM level must be a-casual/true random/stochastic/non-deterministic, i.e. Local Hidden Variables doesn’t work either in theory or experiment.
Now, if we bring in a "FTL mechanism" as an explanation to what goes on in Bell test experiments – that doesn’t work either! Since a "FTL mechanism" brings cause* to Bell's theorem, where cause is forbidden!
Get it?
