BA needs to provide chauffeur service to F passengers when their plane is departing from a remote stand. They could also provide same from T5 CCR if the pax is on a flight departing T3, just drive them there instead (I mean my JFK flight last weekend was closer to T3 than T5), and then they don't need the F facilities at T3; ALL F pax to go T5, like the Lufthansa First Class Terminal.
