@neauoire if there ended up being tools using this as their interface, i think it'd be super useful in gur case of using a machine made from salvaged parts, if you can't get your hands on an lcd + ascosciated parts and don't have / can't power a monitor (or dont have video generation circuitry), you could build a basic terminal as a grid of 7 segment displays.
you could even wire gur LCDs yourself and put a basic stencil over it to make one from scratch.
