Indeed, but even if they appear as cameos, the game would still have to go through your save file and figure out which ones are dead. If that is the case, why not take things a step further and make the survivors squadmates. As for gameplay experience, that's why i assume there will be new characters as well. I personally would be interested to see Aria as a squadmate, and perhaps Harkin. With the Reapers invading, Shepard will pretty much need an army. Thus, I assume that regardless of who the teammates will be, there will ba a lot of them.
