[Bug]: Missing clarification for unstable_batchedUpdates behavior

Summary

The documentation does not clearly explain the current behavior of unstable_batchedUpdates, which can be misleading for developers.

Details

While reviewing the React DOM source code, I noticed that unstable_batchedUpdates may behave as a no-op in modern React configurations (outside of legacy mode). However, this behavior is not clearly explained in the documentation.

This can lead developers to assume that the function still provides batching behavior, when in practice it may not affect updates in modern setups.

Suggested improvement:

• Clarify when unstable_batchedUpdates is effective
• Indicate that it may behave as a no-op in modern React
• Provide guidance on whether it is still recommended for use

This would help prevent confusion and improve developer understanding of the API.

Issue で指定されている react.dev/reference/react-dom ページから始め、現在の unstable_batchedUpdates のドキュメントを、モダンモードおよび legacy モードでの動作と照らし合わせて確認します。ページで batching が有効になる条件を説明し、no-op になる可能性に触れ、開発者が使用すべきかどうかについて明確な指針を示せば完了です。
