I see from the airport website that you can now book their new " meet and greet" car parking facility. It says, leave your car in one of the designated bays outside the terminal, where you will be met by a member of staff. Your car will be waiting for you, just feet from the terminal, upon your return. Seems to cost about £40 for one day.
I can't believe this facility is already available, when work on the new drop off zone, in the short term car park, has only been running for about two weeks.
