What's the present most popular consensus about non-locality and spacetime? Is it since the wave function is not something physical, there is nothing there in spacetime to be non-local about. So let's just extinguish the concept of physicality this means we just treat wave function and spacetime as just equations and don't try to have physical picture of it, and this thinking is enough to put it under the rug?
To get in the mood. The following is interesting stuff from March 2009 Scientific American article called "Was Einstein Wrong? Quantum Threat to Special Relativity":

And it is the wave function that lies at the heart of puzzles about the nonlocal effects of quantum mechanics. But what is it, exactly? Investigators of the foundations of physics are now vigorously debating that question. Is the wave function a concrete physical object, or is it something like a law of motion or an internal property of particles or a relation among spatial points? Or is it merely our current information about the particles? Or what?
Quantum-mechanical wave functions cannot be represented mathematically in anything smaller
than a mind-bogglingly high-dimensional space called a configuration space. If, as some argue,
wave functions need to be thought of as concrete physical objects, then we need to take seriously the idea that the world’s history plays itself out not in the three-dimensional space of our everyday experience or the four-dimensional spacetime of special relativity but rather this gigantic and unfamiliar configuration space, out of which the illusion of three-dimensionality somehow emerges. Our three-dimensional idea of locality would need to be understood as emergent as well. The nonlocality of quantum physics might be our window into this deeper level of reality.
