It kind of makes sense if you relate it to ASCII art, which is very often not ASCII for similar reasons. The naming evokes that concept for me at least. Naming is hard in general, I'm sure they tried to find a name that they thought worked best.

I agree that "TUI" is a better fit though. But not TUI-driven-development, more like TUI-driven-design, followed by using the textual design as a spec (i.e. spec-driven development) to drive GUI implementation via coding agents.
