As a general principle, determinism is meta-physics. I doubt that it can be
strictly falsified because every possible test depends on auxiliary
one might be willing to give up before declaring a general metaphysical

determinism has been falsified. Quantum mechanics showed experimentally
*local* deterministic theory can be right. So the principle of determinism
with the principle of localism (no faster than light signaling).
Determinism can be
saved by introducing non-local theories, like Bohmian quantum mechanics or
ISTM MWI is local but multi-valued, but local (no information travel faster than the
speed of light).
I think it depends on the model of MWI. If you take Everett's original idea then a split
due to a measurement "here", splits the wave function of the universe everywhere. Of
course it's "local" in the Hilbert space where it's just a different projection. If you
consider a decoherence model then the "split" propagates out from the "measurement"
event. If you consider the multiverse model, then nothing physical propagates, you just
learn which universe "you" are in (which was a non-local hidden variable).
