Perhaps a 3rd experimental proof is already in. Notice in this Wikipedia discussion of the vortices that a superconductor can be taken to its transition temperature and become superconductive, yet as the temperature is lowered even more so, the resistance magically appears again, although a small resistance and no longer zero resistance.
Now is that explainable in the Malus law theory of superconductivity?

The Malus law theory can explain the state of "vortex glass", as being a interference in the polarization of the atoms of the material. There is only one angle in which all the photons go through in polarization -- 0 degrees, so as the temperature reaches transition temperature we have the 0 degree polarization. As we lower the temperature even more, we interfer in the polarization angle and thus some photons are blocked. As we lower the temperature more, we again align the polarization to 0 degrees.
BCS theory offers no explanation.
