7. It allows users to call methods with specific input parameters and receive output from the remote service.
8. Users can also monitor the message bus and track sent and received messages between different processes.
9. Busctl supports examining and modifying the security policies associated with D-Bus services.
10. It provides a comprehensive and powerful interface for managing and interacting with the D-Bus system bus in a command-line environment.
