As someone who worked in a decently sized company working on a software product written with TS/HTML/SCSS (at least we had those) and jQuery: no, absolutely not.

as the apps get big, state becomes a mess, fully reusing code is very hard, making anything even slightly reactive becomes not only a lot of code, but a jumbled mess of mutability, usually copy pasted from somewhere else. I will take any other type of app over that - I don't care if it's angular, vue, react, next, whatever.

So i contend that not only is "managing a bit of state and writing sensible CSS to make it reusable" very hard, I haven't even seen it done ever, at least in my personal experience of the code I touched
