MME is never going to be a large airport, we all know that. However many passengers liked the idea of a few paces from entrance to aircraft, not having to go through a maze of duty free shops and then trying to get a seat airside. Some might argue that buying in duty free is cheaper, however most super markets are able to offer similar pricing. I can't see the need to spend a large amount of money on the passenger terminal, check in and security would cope in the short term.
