A lot of people revisit these works later in life and have even further appreciation of them. I think it all validates the goal is to teach learning as a life skill. Learning is never complete. Even things you know, you may not understand until later. It’s all part of the process of learning to learn and emphasizing curiosity and critical thinking. These are the high level objectives of education and inform a lot of the processes that exist.
I’m in my fifties and taking a break from work and have now found myself reading Macbeth, Doctor Faustus, along with Gibson’s Sprawl trilogy. My movie watching is now much more auteur and reaching for the unconscious and immaterial experience.
I’ve wonder if I was taught Shakespeare too early, but see it more as an Easter egg or gift waiting for me to catch up. I think more so I was so focused on the rational I was ignoring the other parts though fully immersed in being the other part. Now I see it and appreciate so much have the right lens from early teachings with my experiences. And to your point continuing to learn.
