Please remember that Web Components are much more akin to an ABI for web projects and not a full-featured framework.

Any web component easily plugs into React, svelte, lit, etc. Existing components written in those frameworks can pretty easily be wrapped in a web component. It's a common base-layer we can all use.

If you attempt to build a web app using just web components and no libraries, you'll quickly find that you're doing lots of manual DOM updates (no templating engine) and lots of manual state management (no data management API).

As an ABI, it's wildly successful. It does, in fact, just work. It's just very low level.

That is why we have a library to make it easier to work with these low level functions: Lit. And because Lit uses these functions, it can be a lot more lightweight compared to React & Angular etc.
