This has a few interesting corollaries, ISTM.
1. It hints that there might be a way to distinguish the pilot wave interpretation of
QM from the rest, which could be handy
I doubt that since Bohmian QM is just another way of writing Schrodinger's equation.
Bohm gave it a certain interpretation different from Bohr's, but mathematically they
must be the same.
?
Bohm added a potential obeying a quite special equation, in addition to the SWE.
It's not in addition. He just divided the SWE into an amplitude and phase part. The
quantum potential term just comes from the solution of the amplitude part.

Bohm gave a non collapse "QM", but a quite different theory than QM.
But it's "non-collapse" because he supposed that particles have some initial distribution
and then follow the guiding field to definite events.
That potential has to act non locally and physically. Also. (of course by Bell
theorem).
In fact that move mirrors the adding of primitive matter and primitive physical laws to
arithmetic.
In this "everything-list" we are supposed to dislike adding equation, or axioms, to make
things judged "ugly" disappear.
Hmmm. I didn't know "we" had a dogma?

2. It hints at eternal inflation (the second bit of support for this in the last few
months, assuming the BICEP results stand up). EI gives rise to a "Level 1" multiverse
which makes the MWI's multiverse redundant, in a sense.
3. It DOESN'T explain how the universe formed spontaneously from nothing, however! It
explains how a patch of false vacuum or whatever which obeys the Wheeler-deWitt
equation could have generated an expanding space-time, and given 2. there is no need
for anything to appear from nothing - we have a steady state cosmos, on the largest scale.
