To be extra pedantic, any app following Apple guidelines will quit on Cmd-Q, it should never (and I've never seen it so) only close a window, and alt-F4 isn't any different than clicking the close button with your mouse. Really the point being, modern GUI applications (hell even not-modern 90s DOS applications) almost universally follow a common set of guidelines that were established many decades ago and have been more or less consistent across multiple platforms for many people's entire lives, vs the land of Vim and emacs and screen et. al. where every app has its own bespoke method of operation. I think there's a benefit to the former even in TUI apps. If i remote into a client's system, or jump on my coworkers laptop, or am setting up a new system, it's good to know how it's going to work.
