Firebase should offer a built-in feature to automatically detect changes to Cloud Functions and deploy only those functions, grouped into manageable batches to avoid rate limits. This feature would streamline deployments by:

• Scanning the project directory to identify functions with modified code since the last deployment.
• Automatically batching the deployment of changed functions based on rate limit thresholds (e.g., 8-10 functions per batch).
• Handling the deployment process transparently within the Firebase CLI or CI/CD integrations, reducing manual intervention.

This functionality would save time, minimize deployment errors, and improve developer workflows, particularly in large projects with numerous functions.
