They've had a limit for quite a while, and they also allow only 1 piece of carry-on luggage for non Matmid Gold/Plat/TPL in Y. That being said, I've gotten away with 2, and the weight is never an issue. Usually, they'll complain at the gate, not at check-in. And there, they'll gate-check for free. Just try and keep carry-on out of the check-in agent's eyes..
