Nothing stops you from using web components in React. There's even standalone (https://github.com/Wildhoney/Standalone) which allows you to transform React components into common web components.

But modelling React into web components makes about zero sense. The spec started many years ago and it is utterly outdated and useless. Web components aren't event components, they are pluggable templates. They expose all the problems and issues that React has already solved. While web components are dependent on vendor policies and specs, yet do a fraction of what a React component does, React is already out there serving apps to mobile, desktops, shell console, watches and so on - because it is what web components should have been.
