they wont work on android though. thats the main reason i started using more TUIs myself. i needed to be able to run a bunch of python scripts on linux, windows and android/termux. or if any of the linux phones ever matures, or sailfish, then the same scripts will run thereas well, probably without any modifications needed
KDE has a framework based on Qt's QML that works on Android. It is called Kirigami. They have written apps and even a complete Plasma Mobile using it. The apps work both on Android and Linux.
Mobile has significant paradigm changes that makes using both terminals and traditional GUIs harder anyway though. I do expect the need for completely different cross-platform libraries for mobile UIs.
It is trying to fit GNU/Linux into Android/Linux, on a model that has only worked so far because internal politics have prevented the replacement of Linux kernel with Zirkon.
The official NDK documentation on what is supported for NDK written code on non rooted devices, and the hurdles that Termux faces to keep running on standard Android images via PlayStore distribution, show why it isn't right.
