This isn't specifically speaking to your point about iPad OS 13, but I actually think that example fits very well to the desktops of the 90s everyone talks about those as thoughtfully designed and discoverable. Kids at the time took the time to learn all it. Parents needed to take classes to learn the basics to do their job. Even now, those former kids get called in when something "breaks."
