Summary: We can tighten our criteria for what is a component by requiring that a component or hook contain JSX or hook calls directly within its body, excluding nested functions . Currently, if we see them within the body anywhere -- including nested functions -- we treat it as a component if the other requirements are met. This change makes this stricter.
We also now expect components (but not necessarily hooks) to have return statements, and those returns must be potential React nodes (we can reject functions that return function or object literals, for example).

babel-plugin-react-compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
