I understand that Bruno is appealing to the notion that Bohmian
mechanics can be considered as a version of the many worlds, where a
single world is given ontological preeminence by the pilot wave, and
all the other branches are not really there.

The "not really there" branches are the ones with the zombies in them
- but that would imply the zombies are not really there too.
