Summary: This only matters when enableTreatSetIdentifiersAsStateSetters=true This pattern is still bad. But Right now the validation can only recommend to move stuff to "calculate in render" A global setState should not be moved to render, not even conditionally and you can't remove state without crossing Component boundaries, which makes this a different kind of fix. So while we are only suggesting "calculate in render" as a fix we should disallow the lint from throwing in this case IMO Test Plan: Added a fixture --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
