It is quite a bit out of date luckily. Signal-Desktop already stores data encrypted for quite a while. However it used to store the decryption key right alongside it. Recently (a few month ago) Signal switched to storing the key within the systems keystore, greatly improving security. Also causing a flood of users complaining that the can’t just copy their .config to a new desktop and retain their chat history. This may have prompted the release of this new feature :)
