I don’t disagree, but to me web components solve a different problem. I want rich widgets without being bound to any particular JS framework and without having to ad hoc it everywhere.

As an example, I still like the simplicity of Rails for basic apps. I also enjoy the numerous component libraries, such as Antd, available for React. I don’t want to have to pull in React just so I can get a reasonable way to work with a Tree widget.

I’m not trying to only use the platform. The components are free to be built with whatever lightweight lib they need (Lit, UI5 Core, etc.). But that’s contained in the component. I’m free to use my framework or web technology of choice for building my app.
