But the point would remain in that case that there is in principle an experiment to distinguish the theories, even if such an experiment has yet to be performed?
Although (and I admit my understanding of the topic is being stretched here) it still doesn’t sound like the central issue of the existance of parallel universes with which we may no longer interact would be resolved by such an experiment. It seems more like Copenhagen’s latest attempt to define the conditions for collapse would be disproven without particularly necessitating a fundamental change of interpretation.
If we managed to put human-sized systems into superposition, that’d rule out CI AFAICT. And before that, the larger the systems we manage to put into superposition the less likely CI will seem.

For Copenhagen, yes, but MWI and Copenhagen aren’t the only two interpretations of quantum mechanics worth thinking about.
In truth, you’ll find few physicists who treat the Copenhagen Interpretation as anything but convenient shorthand, not usually for MWI.
