Document Why a "complex expression in the dependency array" Is a Problem

this is about the exhaustive-deps eslint rule, specifically her: https://github.com/facebook/react/blob/master/packages/eslint-plugin-react-hooks/src/ExhaustiveDeps.js#L779. i've been trying to find out why having a complex expression inside of the dependency array is bad, but haven't found anything saying why something like [err?.message] would cause issues. is there somewhere it's listed in the docs that i haven't seen?

まず、packages/eslint-plugin-react-hooks/src/ExhaustiveDeps.js の779行目付近にある exhaustive-deps ルールの実装を読み、依存配列に関する既存の React ドキュメントを確認してください。[err?.message] のような複雑な式がなぜ問題になるのかを、読者がルールを理解できるだけの十分な説明とともに文書化してください。適切なドキュメントでその理由が明確に説明されていれば完了です。
