I think you pointed out the problem.

I suspect it has the same problem as ncurses: Not easy to learn, get proficient with, or rapidly produce something decent with.

I've been working on a project for a while that allows running any console program within it, and use text, keyboard, or mouse triggers to add a VT100 TUI, but it's uncomfortable to learn, very hard to get proficient with, and while it's possible to rapidly produce something decent, you're going to hit a hard wall producing something excellent.
