Are they as accessible as GUI though (genuine question)
UI libraries have a lot of features for allowing people with disabilities to “read” and interact with the screen in efficient ways
Accessibility is a great thing to have and strive for, but it cannot be the number one design principle.
Imagine if everything around us would be designed for blind people.
TUI tools are generally as accessible as the terminal on which they run.
GUI apps are much trickier. They require that the developer implement integration with accessibility frameworks (which vary depending on X11/Wayland) or use a toolkit which does this.
