Our club requires the same- you still have to put your AMA card in a slot reserved for 2.4 GHz, but don't have to take a pin. Checking the board should still be a habit of everyone at the club, regardless of what band you're using. To me it's as automatic as checking traffic before I pull out into the street. I have a 9C that most of my planes are on, and I'm not changing any of them, but I just bought a DX-7, and whatever I get from here on out will go on it.
