I understand it not being needed for online squadron flights, as they can organice themselves but with single player things change a lot.
I've done a test today filling up the carrier with IA, and because they just go about their business, it means that you are stuck in a mess of airplanes going through the deck and you have to force your way in, and therefore your wingmen won't be launching at the same time as you, mixing flights and such.
Over multi-player online servers, it gives the opportunity to self-organization to improve the overall quality of experience with this module.
Please consider adding it back, as it was a really nice addition to sort things out
