I have flown into Redhill with regular here (JohnR81) and it looks to me like those rules are the start of someone trying to close it. Of course, it is a perfectly good airport, but it now has neighbours. Who despite the airport being there "day one", want it gone now.
Disgraceful left wing lunacy.
No one wants helicopters until they need to be rescued (from various things). Same in AUS.
