The UIs are text only, so they are textual. Modern TUIs may support mouse events. That this tool can export to several TUI frameworks is evidence that these UIs are indeed TUIs, even if not the most traditional.

It clearly cannot. Have you even tested it?
No, a text-based UI is not sufficient. It must also work in a text-only session e.g., on the CLI over SSH.
“Modern TUIs may support mouse events” hah! They already did in the 80s…
