Yes, it feels like it's only getting more complex and for the sake of somewhat limited use cases (like your basic JSON/HTML editor apps, or displaying data fastly). What I'd like to see is support for more general, compiler supporting infrastructure. A platform where you could develop your domain specific languages and data structures that are then transformed to native environment. Kind of like JavaScript is used as a transpiler target, but you still need to have loads of functionality on top of browser base. Then there could be ways to tag your data with semantics (this text is a heading, this is a link), accessibility, editorial intents (text select, copy/paste) that browser could use to display for specific devices and provide interaction (typing, touch). Since browser is a place to present and produce almost everything digital, not one standard body nor a standard can provide this. HTML/JS/CSS was borne into what it is today for few, narrowly scoped purposes and is creakingly, laboriously converted into different thing each time you open a web app.
