You will most likely be able to uninstall exFAT support. The problem is this is a kickstarter/IGG campaign, not pick-and-choose what you want. Noone is asking you if you would like to throw away the camera and a bit lower RAM and pay 150 for it, because you plan to not use the whole lot and rarely take pictures. It's a package, if you don't want to use some parts, great, others will. I would understand this whole debacle if they suddenly raised the price by 3$ or something, without asking, but they did not. In the price you agreed to pay you will have an extra, throw it away if you like
