I agree. So many TUIs from webshit devs don't even bother to call isatty, let alone check terminfo to see if ANSI escape codes are even valid for this terminal.

But modern open source subscribes to Mao's Continuous Revolution Theory. Calls for some measure of stability and sanity are usually dismissed with some form of the argument "awwww, is poor diddums afwaid of a widdle change?" Or in this case, "still using vi on your ADM3A, old timer? Our software is not for you."
