While true, my main point is that literary canons…including the Western canon has not been a monolithic set of writings set in stone…but has been evolving over the decades and centuries.
Ironically, one recent example of a possible addition to the worldwide and Western classic literary canon is a group of Ancient Egyptian works:
I agree that the canon has never been set in stone, but I think you’ll agree with me that recent decades (since, say, the '60s or so) have seen a far more rapid (and broad!) expansion of the canon to include works that would never have been considered 100 or so years ago.
I had so much Western Civ in high school and before I was very happy to be able to fill my social science requirements in college with something else. The Chinese Civ course was fabulous. So was the women’s history course.
One of my favorite electives in college was a history of 20th century labor movements. Really eye opening.
