Does a basic roasted potato recipe actually teach you something useful?

Wondering if roasting potatoes counts as a foundational technique in any real sense. You're learning how dry heat works, how surface moisture affects browning, how fat distribution changes the crust. Those are principles that carry over to a lot of other things. But it also feels almost too simple to qualify, like the technique is hiding inside something so familiar that people don't notice they're learning it. Curious whether others think a well-executed roasted potato teaches you enough to earn a spot on a list like this.
