AFAIK, the search & rescue aspect is the same for IFR and VFR. ATC has
nothing to do with it, except that when an IFR flight arrives at a towered
airport, the controller contacts the FSS (who is the entity waiting for the
"timer to go off") to close the IFR flight plan on the pilot's behalf.

That's funny, a tower calling FSS to cancel an IFR flight plan.
