Terminals are full of hacks. For example, in my terminal project linked above the Readme says this:

"Backspace is known to not work in some configurations. As a workaround, typing ctrl-h tends to work in those situations." (https://git.sr.ht/~akkartik/teliva#known-issues)

This is a problem with every TUI out there built using ncurses. "What escape code does your terminal emit for backspace?" is a completely artificial problem at this point.

There are good reasons to deal with the terminal: I need programs built for it, or I need to interface with programs built for it. Programs that deal with 1D streams of bytes for stdin and stdout are simpler in text mode. But for anything else, I try to avoid it.
