In E&M, Yes, but surely not in QM. When we got to Maxwell's displacement current, the professor did some hand-waving related to delta functions, which was very unsatisfying. A good course in E&M would, IMO, include a rigorous discussion of Planck's BB formula, since it is where quantum physics begins, and including a rigorous treatment Maxwell's displacement current and wave solutions of the Maxwell's equation. I doubt you have had a good course in QM, and in physics in general, since you deny that theories of physics start with postulates, when they obviously do.
