I’m disappointed they went with React as well. There are definitely more innovative frameworks (my favorites: Vue and Svelte). But I do understand the Tailwind team - it is an economic decision. React (still) dominates.

Going framework-agnostic is (currently) not a good approach imo. The developer experience would suffer too much. I hope in the future agnostic UI kits become a thing, but the tooling around this approach needs to change first.
