The point of releasing the SDK is so that maps can be made faster by the community than RRG can make themselves, without giving all the tools to make it functional. This will let them put more attention to the aircraft. Enough will be provided to make the land, but the final conversion process of it to let it plug into DCS/DCS WWII will be done by ED or RRG. This would act as quality control, which is in my opinion a good thing.
