> Have you _never_ looked at any UI toolkit in existence, ever ?

Funny that you say that, I actually did my PhD on this topic! You can find a state of the art of UI toolkits, from page 28 to page 96 of my PhD manuscript. https://hal.science/tel-01455466 I wrote it in 2015, so it's dated for sure. But short answer is: Yes I have been looking at A LOT of UI Toolkits, and one thing I am sure of is that you clearly are blissfully unaware of the socio-technical aspects of Toolkit adoption.
