To the extent that MWI applies then nothing is counterfactual so might as well use that as a synonym for “decoherent” to bridge the differences between ontologies.
The past is not exactly classical and to the extent it is “merely” classical-like that data extraction hope is possible.
The “WW2 never happened” portion would have its own classical-like past so calling it “right now” doesn’t seem obviously proper. Sure the crosstalk parties make more sense to be existing on the same level rather than betwen a real and not real party. But like I would not count neutrinos passing through me as part of my body I would not count that “other side of the wavefunction” to be part of my immediate experience.
I do wonder if somebody wanted to maximise the amount of crosstalk possible what would be the limiting factors.
