In Norway itīs not a rule, but we mostly ask aircraft inbound unmanned aerodromes on a VFR flight plan how they intend to close it.
"....G-XXXX do you intend to close your flight plan with us on radio before landing or via telephone on the ground after landing...."
Or some such phrase.
Saves A LOT of spurious overdue actions, since the overlying CTR, TMA or ACC controller is responsible for closing the damm things.
When ETA is passed with 30min our radar/FPL system gives a "SAR alert" on the relevant flight if it has not been closed.
