That's about right. Yet, I think BSH (HAM) will continue to maintain their GUIs on a daily basis since they will want to keep older devices up to date with their IoT ecosystem, too. In the past, once a UI for appliances was written, it stayed the same until the appliance broke down. In a world of IoT, code will become updated on a regular basis. That's why I was questioning the initial development costs vs. maintaining an application's GUI until its EOL. I wonder Espruino was not mentioned so far. Their approach could speed up dev time by a lot.
