Not sure if it is a similar idea you're thinking of, but we have a procedure here in Canada when approaching an airport on an IFR flight plan, we have to report clear of the active runway when landing at an uncontrolled airport or airfield. This is because the controller may not have radar down to the ground, but is still responsible for the flight plan and alerting services, even though we will be off frequency talking to the local traffic.
The pilot can elect to cancel either the provision of IFR services and/or the alerting services if they are able to proceed with reference to VFR. Normally this is done to free up the airspace for other inbound or departing traffic.
When landing at a controlled airport or an airport with an operating flight service station, this report is not necessary as the flight plan and alerting services will be terminated by the controller or radio operator upon landing.
