A sample use case would be for HFP handlers (e.g. pulseaudio commonly in Linux system or CRAS in Chrome OS) that has the battery information reported via HFP extensions. This patch series also refactors the existing battery API to be split into internal API rather than GATT BAS specific. This way internal plugins can also make use of convenient functions to reliable register battery objects. The battery information is then exposed via the existing Battery1 API. Many UI components already consume this so they will be able to display many Bluetooth peripherals' battery information via a unified BlueZ API.
