Well, the updates do not only fix bugs, they also feed in new satellite imagery or replace parts of the ground texture which were not covered by satellite or aerial imagery before. As well as improved DEM data. Generally, this is to be welcomed, of course. The sim is not designed for historical sceneries, and the SDK does not provide easy tools for controlling vector or imagery data (e.g. removal or addition of roads / vector data or landclass data). FSX / P3D was much more flexible in that regard.
