I think the title is misleading. There was xdialog 20 years ago. And libnotify has like 15 years too. I understand "modern bash" as in any other scripting or programming language: It's about what caveats of the language quirks, the optimizations and the failure scenarios, that you solve with your code conventions, which people didn't use to use, some years ago. Change things for the sake of having something "newer" available for me, is something I try to avoid at all levels of my life.
