Well, sure, but I never heard of anyone postulating that.

QM also has probabilities that cancel out, such that there's zero 
probability of something happening in a combination where either individual 
event could happen. E.g., electron 1 might go to location X[*]. Electron 2 
might go to location X. Electron 3 might go to location X. But there is zero 
probability that all three will go to location X. Also, the likelihood that 
a photon will go somewhere far away at anything other than very close to the 
speed of light is zero (and not just very low), because the probabilities 
actually cancel out. You don't need to postulate an upper size on QM 
locality to get impossible events. And when "improbable" is "1/10^500 that 
any particle in the universe will ever do that", then yeah, that's pretty 
much impossible too.



[*] "location" in spacetime, i.e., an "event".
