Super helpful for basically anything in a terminal. Stuff is going to flow by pretty quickly or at least keep bumping the terminal every couple seconds, usually when you _least_ want it to do so. Reading off whatever your program emitted while it's pushing the terminal up every half a second gets really annoying without Ctrl-S. It's probably the most used terminal shortcut after Ctrl-C for me.

That's a fine argument, but not relevant for when you're in an editor -- and modern TUI apps disable XON/XOFF for that reason.
