Having been through the track a few years ago at a reasonably large university, it was somewhat limiting that the teaching style basically pushed the narrative that "these people thought this stuff a while ago but they were wrong and here's why, so shut up about it lest you be made a fool." It totally kills the inquisitive and investigatory nature that is the field of physics. A side-effect to this, too, was that when students aren't testing the boundaries and running into all these limiting cases with their own inquisitions, they don't get the kinds of insights that really make understanding physical systems intuitive. For instance, did you know Hamiltonian systems must have an even number of dimensions? It makes sense now that I think about it wrt Newton's 2nd, but I learned this last week in a graduate-level math course.

I'd love to see more of a seminar-type setup for courses where every week an investigation is done and yhe students try to figure it out, while the teacher provides a gentle nudge in the right direction when mistakes are made along with the lessons learned from history. IMO this would make for a much more solid understanding of the scientific method and progress re: "standing on the shoulders of giants."
