Personally I think that if the airlines are going to charge for checked bags they should EXPECT that passengers will try to get away with the largest carry-on they can get away with. With that in mind they should actually enforce the carry-on size limits BEFORE passengers board.
Perhaps establish official size dimensions for carry-ons and make an official “carry-on” friendly icon, like TSA did for laptop bags that can go thru scanners without having to take the laptop out.
