@mntmn Yes! And also, I'd argue there's a cultural reason.

When I first started using a libre desktop, xscreensaver's customizability, while seemingly unimportant, really helped me *feel* a sense of being able to be part of my computer. I'd argue this feeling and experience and sense of whimsy is actually really important for fostering a drive of curiosity. Screensavers, especially those with lots of little fiddly knobs, are a great low-entry way of getting people to experience that.
