The problem with such a focus on smallness and simplicity, particularly at higher layers of the stack, is that it requires throwing out lots of people's must-have features. For me and my blind friends, that feature is a screen reader. For someone else, it's right-to-left or bidirectional text rendering (hello TrojanSource). For someone else, it's complex writing systems or support for Unicode characters outside the Basic Multilingual Plane. And so on. I doubt that any UI framework that fits in 5000 lines of code or less would support all these things. Sure, some of the complexity in the industry can be eliminated, but some is truly necessary. One good thing about Rust mirroring the complexity of the industry is that at least one Rust GUI toolkit, Druid, is taking accessibility and internationalization seriously. (Disclosure: the team at Google that's funding a lot of the work on Druid is also funding me to work on accessibility.)
