While we only shut down after a method call completed or (if the interface has signals) the sender disconnects from the bus, services may need to inhibit auto-shutdown for more specific reasons themselves, for example when a method call kicks off an operation that should complete before shutting down. Add hold() and release() methods like Gio.Application for those cases. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1115
