I feel this approach is flawed. In theory it'd have been possible to come up with Relativity by recognizing the Lagrangian transforms that match experimental outcomes and say "That's just how it is". Einstein provided an insight as to why that's far more enlightening.
To me, QM is still in the former state, detailed equations looking for a soul.
Here's Feynman talking about it.[1] "We interpret the intensity of the wave as the probability of finding a photon".
