Details:

This new capability further integrates SharePoint Online with Purview sensitivity labeling. SharePoint Online document library owners can set a new type of default label on the library, which automatically applies that label to all unprotected Word, Excel, PowerPoint, and PDF files within the library. This simplifies labeling in bulk across document libraries in an organization, enriches DLP and Copilot with signal to allow admins to monitor and restrict access to this content, and enables inheritance of sensitivity labels to output artifacts in Copilot.

Default Labeling Implementation
If the default labeling is implemented without proper preparation, users may find their documents automatically labeled inappropriately, leading to confusion and potential data access issues.

Integration with Copilot
Without preparation, the integration of sensitivity labels with Copilot may lead to unexpected behavior in document generation, causing users to receive incorrect or restricted content based on misapplied labels.
