Summary:
This brings the behavior of ref mutation within hook callbacks into alignment with the behavior of global mutations--that is, we allow all hooks to take callbacks that may mutate a ref. This is potentially unsafe if the hook eagerly calls its callback, but the alternative is excessively limiting (and inconsistent with other enforcement).
This also bans *directly* passing a ref.current value to a hook, which was previously allowed.

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.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
