I'm quite happy to admit that I don't know the classical-quantum CQ programme well, and certainly not well enough to hazard a genuinely informed opinion that might take the form "it's a candidate for a fundamental theory" or "it's a candidate for a better EFT". I think I can say it isn't obviously not one of those, though. Also, I'm not ready to sloganize the work beyond "it's complicated". A good entry point to CQ is Oppenheim's [hep-th] https://arxiv.org/abs/1811.03116 "... invariant under spatial diffeomorphisms ... consistent ... completely positive, norm preserving, and linear in the…
