But to the average digital forensic examiner (working for police, lawyers, corporate investigators etc.) it means rather than having to use a separate tool (or asking a more technically qualified analyst to assist, or missing them altogether), Signal related artefacts are now processed and presented alongside everything else that Cellebrite PA supports (i.e. other built-in and third-party applications, media files, OS logs etc.). If they don't support Signal already, the dozens of other commercial and open-source forensic tools and their customers will benefit from this article soon, as will the poor folks responsible for maintaining quality standards in forensics labs (such as ISO 17025).

EDIT: Example of a Cellebrite competitor with similar a capability: https://blog.oxygen-forensic.com/115-2/ ("Oxygen Forensic® Detective enables extraction and decryption of encryption keys from the Android KeyStore on Android devices that are not using hw-backed keys in the encryption process.")
