I believe that if someone is not departing on a flight from Terminal 7 (the terminal you'll be using), security will give them a hard time (i.e. not allow them to go through). The RCC is after the security check-point.
At one time, security at JFK terminal 7 checked boarding passes assiduously prior to passing through the checkpoint. However, this requirement has been relaxed for over a year, a little before the RCC itself wound up on the gate side of security. I usually find myself in this terminal every few weeks and have NEVER been asked for my boarding pass since the renovation was complete. Hence, I would be very surprised if guests encountered any problems.
