I don't think we're waiting for some new concept that is missing. I've been hoping for someone to maintain some popular js library implementing real functional reactive programming and arrows (like https://hackage.haskell.org/package/auto), but I can live without it.
I'm just waiting for something polished, with a small, simple, codebase (not React with fibers, yes to something like solidjs, preact) with widespread types support (not Typescript and the quest for implementing types for every dependency), ideally not creating huge bundles (I like solidjs / svelte), with a core solution to manage state (I like Elm), ideally supporting CSS encapsulation and semantic css (I like CSS modules, MaintainableCSS), mainstream enough that I can hire people to work with without having to become a teacher.
I think Elm got 90% there, but it failed hard on the community side.
I'm thinking of moving to a Rust framework (eg. seed-rs) next as soon as they get popular enough and after checking whether the wasm bundle size make sense.
