Something else that doesn't seem to get a lot of attention in terminal UI is screen reader accessibility. I'm not a regular screen reader user but I've tried a few TUI programs in GNOME Terminal with Orca and it was a mixed bag. Some simple programs were actually usable, more complex layouts not so much. It seems GNOME Terminal outputs the line where the cursor is when it changes so it also depends on if the program puts the cursor somewhere relevant when it finishes updating the screen.
