> That sort of design has fallen out of favor with newer frameworks, unfortunately. The new preferred style seems to be a wireframe that the dev chooses which parts fill in, and often only the barest of essentials makes the cut.

This is even more visible when using Apple’s own apps on macOS. Choose any of them that have been ported from iOS without any attention to detail or any QA for accessibility, like Reminders or Settings or Notes or another app. The tab key will not take you where you might expect. There is no way to navigate only using common keyboard shortcuts. Nobody working on all these Apple apps have heard of tab order or keyboard based navigation.
