The home button was a nice UI affordance, but it tended to fail after a few years. Every old iPhone and iPad that my parents used had home buttons that didn't click correctly - an minor annoyance in the years where upgrading your phone every two years was normal, but not for the present where people keep their devices for much longer, especially iPads with a much bigger battery. I never had a device with the solid-state home buttons (like the iPhone 7 and 8), but I assume these were not an option due to cost.
