G-IR currently lacks an annotation for associating async calls to their _finish counterparts. As a result, vala's binding generator assumes that corresponding function is just function name - _async + _finish. This holds true for 99% of the time, but not here, because nm_device_wifi_request_scan_options_async uses nm_device_wifi_request_scan_finish instead of expected nm_device_wifi_request_scan_options_finish (sharing it with nm_device_wifi_request_scan_async). As such, a metadata entry is required to point vala to correct finishing function. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/1114
