I've had radar facilities chase me down after I've lost comms with them
during VFR FF. They want to make sure they didn't lose you and something
bad happened to you (like you crashed). Just consider it
an extra service.


It's not necessarily an extra service. If radio and radar contact is lost
in an area where ATC would expect to have both, then ATC is supposed to
chase you down.
