(author from Mux here) -- that is correct. For the stuff we build for in-house use on mux.com and dashboard.mux.com we have a components library written in React.

You nailed it that we are shipping SDKs with visual components (like a video player) that need to be compatible across all kinds of frontends.

Instead of N number of SDKs to maintain where N is every front end framework, we have 2: a web component, and a React wrapper around the web component. Maybe in the (near) future we only have to maintain 1.
