Yes. But also, those were changes in the required core courses for freshman. Just as English departments dropped their “Great Books” courses in favor of postcolonialism and gender bending, Harvard Law dropped its core courses for freshman, which had been taught to every law student since the law school was founded.
No doubt you can elect to take a course in constitutional law, but it is not required as a basic core course. And if English Departments are any clue to the future, then in future years it is possible that as current faculty leave or retire, they will no longer have any faculty left who are competent to teach Common Law.
Harvard used to have a great English department. Now, only one professor out of twenty is worth taking a course with. And the same thing has happened in most other humanities departments. In the German department, Goethe has been replaced by German films. In the French department, Rabelais has been replaced by Sartre.
